A character -- frequently male -- who is only able to make one specific kind of food, often because they're a LethalChef and attempts to diversify their efforts would end in disaster. Through [[TrainingFromHell harsh training]], they have finally become able to make ''one'' thing that is edible, at least. If it's their TrademarkFavoriteFood, they're in luck. Sometimes their specialty dish is widely praised as being transcendentally delicious... they just can't transfer that skill to anything else.

Sometimes TruthInTelevision -- it's relatively common for people who aren't particularly good at cooking (even if they're not quite at LethalChef levels) to be able to make a few dishes fairly well. This trope lies somewhere between SupremeChef and LethalChef. Also see CripplingOverspecialization for other non-culinary examples.


[[folder:Anime and Manga]]
* Saati in ''Manga/AILoveYou'', after learning to cook, can only make curry, even when she tries to make something else.
* Both Shirayuki and Obi have a downplayed and discussed version of this in ''Manga/AkagamiNoShirayukihime''. When they get stuck cooking for the rest of the main group, though it's actually just supposed to be Obi who roped her into helping him, Shirayuki says she can only cook simple food fit for a bar since she was raised at one and all of Obi's dishes are spicy and immediately recognizable as his. They're both cooking multiple dishes but they've each got a limited repertoire of dishes they know how to cook.
* Despite the characters from ''{{Franchise/Anpanman}}'' that are themed around prepared foods and meals being [[SupremeChef the best]] at whatever they cook, this is the ONLY thing they cook. Compared to characters with a single ingredient theme (like a single vegetable or fruit), this leads to a lot of episodes based on two of these characters battling over whose dish is the best. This is also the driving point of practically every argument the Donburiman Trio has gotten into: which donburi dish is the tastiest.
* Meiling from ''Manga/CardCaptorSakura'' is excellent at making Chinese food, but really bad at making any non-Chinese dishes... ''[[RunningGag specially]]'' [[RunningGag baking]].
* In ''Manga/GourmetGirlGraffiti'', Kirin's mother only cooks fried produce.
* Haruna in ''LightNovel/IsThisAZombie'' can only make fried eggs... but they're ''[[ImpossiblyDeliciousFood really good]]'' fried eggs.
* In ''Manga/{{Kannagi}}'', Tsugumi enjoys cooking. She can make eggs, vegetables, and [[BreadEggsBreadedEggs eggs]] ''[[BreadEggsBreadedEggs with]]'' [[BreadEggsBreadedEggs vegetables]].
* While she starts out as a LethalChef, Yui in ''Manga/KOn'' once had to take the reins of house-duty when her sister [[TheCaretaker Ui]] was sick. While Yui couldn't do all that much on her own, she did teach herself to make a mean [[http://japanesefood.about.com/od/rice/r/okayu.htm okayu]] to help Ui get better. She later used this same knowledge to help Sawako, who was also sick.
* Umi Ryuzaki from ''Manga/MagicKnightRayearth'' claims that she is excellent at baking, "but terrible at anything else".
* Ringo Oginome of ''Anime/MawaruPenguindrum'' starts the series only being able to make [[TrademarkFavoriteFood curry]], but learns how to cook more things under Himari, Shouma and Kanba's tutelage. It also serves a metaphor for her CharacterDevelopment, since curry represents her clinging to her past, and specifically [[spoiler:the memory of her dead older sister Momoka, who loved curry to death]].
* Nana's mother in ''Manga/NanaToKaoru'' can make rice omelette. ''Just'' rice omelette. It's still a step up from [[LethalChef her daughter]].
* Akane Tendo of ''Manga/RanmaOneHalf'' is a LethalChef, but it's said that when she really tries her curry is bearable, "Maybe... even tasty."
** Ukyou, who is otherwise considered a SupremeChef, ''rarely'' bothers cooking anything that isn't okonomiyaki. To the point that when she tried to give it up, she suffered withdrawal symptoms and ended up cooking ''Ranma'' like an okonomiyaki.
* ''Anime/RevolutionaryGirlUtena'''s Anthy sticks to shaved ice. Any other meal she cooks up tend to have [[FreakyFridayFlip very interesting side-effects]], which may or may not be intentional.
* Shana of ''LightNovel/ShakuganNoShana'' only makes melonpan, and packs her lunchbox full of it. Then again, it's her [[TrademarkFavoriteFood signature food]], so she probably doesn't care, and her guardian, Wilhelmina, was a far worse LethalChef.
* One episode of ''Anime/SailorMoon'' has Usagi trying to cook and failing badly... until she makes curry, which Mamoru and Chibi-Usa both enjoy, the latter even asking "Can we have this every night?" [[NegativeContinuity In the rest of the series]] she's a LethalChef - ''especially'' when it comes to curry.
** Rei herself isn't much of a cook either unless it's food that comes prepackaged like curry. In one episode when the girls went on a picnic, Rei teases Usagi's shoddy attempt at home cooking leading to Usagi pointing out that at least she tried while Rei just bought fast food. In a later episode during Rei's little ImagineSpot of the things she ''can'' cook, like instant curry, she's shoved all the packages inside a food processor ''without even opening them''.
* Nerine of ''VisualNovel/{{Shuffle}}'' can't cook, but after taking cooking lessons, she is able to make omelets (and only omelets) for lunch, in large quantities. Before she took lessons, her cooking attempts usually [[LethalChef resulted in explosions and something worse]], so when she finally learned how to cook omelets her dad wanted to create a holiday to celebrate.
* This is practically a plot point of ''Manga/YakitateJapan''. Azuma can only make bread, and gets himself into trouble when part of the Pantasia's Newcomer challenge require him to cook yakisoba. Considering the sheer variety of bread Azuma can make, this might also fall under WhenAllYouHaveIsAHammer.
* According to his mother, [[TigerAndBunny Kotetsu (AKA Wild Tiger)]] loves fried rice so much that he never learned to cook anything else.
* Hoto Cocoa from ''Manga/IsTheOrderARabbit'' can only make bread and related food, but she's really good at it.
* ''Manga/MyMonsterSecret'': Aizawa is, at best, a mediocre cook. Except when it comes to cakes, which she can produce with SupremeChef level skill. Oddly, she herself doesn't seem to be aware that her cakes are far superior to her other food, even when other characters point it out.
* ''Manga/DailyLifeWithMonsterGirl'':
** Miia is usually a LethalChef who's cooking represents a threat to anyone who eats it, but she actually can cook eggs pretty well.
** Centorea is a good cook by centaur standards, but since centaurs are herbivores, her food is generally limited to raw vegetables and salads.

* Calvin's Dad in ''ComicStrip/CalvinAndHobbes''
-->'''Calvin's Dad:''' Since your mom's sick, I'm making dinner tonight.\\
'''Calvin:''' '''''You''''' can cook? \\
'''Calvin's Dad:''' As you can see, I survived two years of my own cooking when I had an apartment after college.\\
'''Calvin:''' Mom says you ate frozen waffles and canned soup three times a day.\\
'''Calvin's Dad:''' Your mom wasn't there, so she wouldn't know. [[NotHelpingYourCase Get the syrup out, will you?]]
* ComicBook/GreenArrow is legendary amongst the hero community in Franchise/TheDCU for his chilli recipe. There is zero indication that he knows how to cook anything else.
** Notably, his chilli isn't necessarily regarded as ''good'', just really, ''really'' hot.
* The only thing ComicBook/{{Empowered}} can cook is blueberry pancakes, although her friends note that they may not be the greatest, they eat them with gusto to cheer Emp up whenever she does cook.
* [[ComicBook/SecretSix Catman]] only ever cooks eggs, though he once claimed he could "also make a mean slab of raw zebra haunch."
* The ''ComicBook/LuckyLuke'' album ''La Diligence'' had a RunningGag where every one of the cooks at the stagecoach stops only knew how to make (the stagecoach says it's copany's mandate) bacon and beans. Taken UpToEleven during the high-class dinner at the end, where they STILL only serve bacon and beans, with some random extra ingredients added for each dish. To say the characters are sick of bacon and beans at that point is an understatement. The only stop that serves something else has been bribed as part of a bet.
** Despite his love of food, Averell Dalton is an absolutely horrendous cook, the only food he can prepare with any degree of edibility is curried eggs (though in ''Dalton City'', Lucky Luke claims that the dish is inedible, though he might just have been screwing with Averell as part of his plan)

[[folder: Fan Fic ]]
* Zuko in ''FanFic/TheStalkingZukoSeries'' can make a very good cup of tea and kebobs but they are the only things he knows how to make.
* Superboy in ''WithThisRing'' is this trope. He's a kryptonian-human hyrbid clone created by Cadmus Labs who programmed him with a variety of knowledge, but for one reason or another, only bothered to teach him two recipes, beef bourguignon and baked pears. This is actually a comic reference, the Silver Age Supermans favorite food was Beef Bourguignon with ketchup.

[[folder: Film ]]
* The remake of ''Film/TheParentTrap'' has the father offer to make dinner for his ex-wife. She's surprised that he's learned to cook. It turns out he can make "pasta... or pasta... or pasta." She plays along and says "the pasta sounds good."
* The older brother in ''Film/{{Zathura}}'' can make one thing: water.
* Riggs, according to ''Film/LethalWeapon2'', only knows how to make chili.
-->'''Riggs:''' Do you like your chili with or without crushed Oreos?
-->'''Rika:''' With, of course!
-->'''Riggs:''' Heh heh. Woman after my own heart.
* The ship's (OK, ''boat's'') cook in ''PT-109'' starts out only able to assemble peanut-butter sandwiches. When asked during an inspection if there is any hot food, he answers affirmatively. The boat's CO sarcastically challenges him, to which he brightly responds "Peanut butter on toast!" Later in the film he's seen fishing - with a hand grenade.

[[folder: Literature ]]
* In Creator/JamesHerriot's ''All Things Wise And Wonderful'', kitchen duties are temporarily taken over by Tristan Farnon, who can only cook sausage and mash - and even that not always particularly well.
** [[StuffBlowingUp His fire-lighting technique needed some work too.]]
* Albert, TheGrimReaper's manservant in ''Literature/{{Discworld}}'' novels, can only make fry-ups. He will experiment with porridge or Hogswatch pudding, but only by frying them. Fortunately, Death doesn't need to eat.
** It's not that Albert can't make anything un-fried, it's that he can't wrap his brain around un-fried food, since that's all he ever eats. The fried porridge thing was considered progress.
*** If porridge is a mixture of oatmeal, milk and water then by adding yeast, letting it work for an hour and then frying it you get Staffordshire Oatcakes, which are more than respectable food.
** He did manage a mug of cocoa once. Well, he was close. If you turned the mug sideways, it would pour out eventually.
** Lady Sybil Vimes can similarly only do a fry-up, and that's usually frazzled, due to her insistence on using [[OurDragonsAreDifferent her beloved swamp dragons]] as her primary heat source. Fortunately, years as a street copper have resulted in Sam Vimes actually ''preferring'' greasy, frazzled food.
** Aimsbury in ''Discworld/MakingMoney'' can actually cook a few things, but they're all fit for a dog to eat (Topsy Lavish, an eccentric old lady, hired him to cook for her MisterMuffykins) and therefore made of odd meats that most humans would rather avoid. He even asks "Have you seen my book, ''Cooking with Brains''?" He prefers cooking for a dog because he has to stay out of professional kitchens due to [[MakesJustAsMuchSenseInContext an allergy to the word "garlic"]].
* Something of a reversal, rather than only making one dish, the cook in ''Literature/AliceInWonderland'' seems to think the only ''ingredient'' is pepper. It isn't elaborated whether or not she is actually able to make anything out of this or not, but given that it's ''Alice in Wonderland'' it is definitely possible.
* Most of Miss Mush's food in the ''Literature/WaysideSchool'' series causes extremely bizarre side effects, so the students avoid it. The exception is milk [[spoiler: and nothing. Some students even got seconds of nothing, but then Miss Mush ran out of nothing.]]
* ''Literature/TheHuntingOfTheSnark'':
-->He came as a Baker: but owned, when too late--\\
And it drove the poor Bellman half-mad--\\
He could only bake Bridecake--for which, I may state,\\
No materials were to be had.
* In a variation, Molly Carpenter from the ''Literature/DresdenFiles'' series is totally incapable of cooking food (Harry claims she once burned a boiled egg), but is very good at [[MustHaveCaffeine coffee]].


[[folder: Live Action TV ]]

* In ''Series/{{Friends}}'', Rachel can only make good brownies.
* In ''Series/HowIMetYourMother'', Lily tells Marshall how delicious his pancakes are and ask if he would like to make dinner sometime. He responds "Sure... how about pancakes?"
* In the sitcom ''Series/{{Alice|1976}}'', Mel's cooking is routinely slammed - even by his regular customers (curious for a diner that's apparently been running for years). Yet, he apparently makes a mean chili. (It sneaks in as a plot point in several episodes.)
* ''Series/LoisAndClark'': "I can only make 4 things, and this is the only one without chocolate..."
* Charlie from ''Series/TwoAndAHalfMen'' tries to learn to cook. He asks everyone how they want their eggs, and no matter what the answer is, he responds "Scrambled it is."
* Debra from ''Series/EverybodyLovesRaymond'' can only cook lemon chicken. Everything else is disgusting. There was an episode titled "Debra Makes Something Good" where she makes braciole. However, she stops making it after that episode.
* Subverted with Luke on ''Series/GilmoreGirls'' - supposedly only cooks diner food, but turns out to be into fusion cuisine and high-end Italian cooking.
* When he travels back in time, the grown [[Series/{{Heroes}} Hiro Nakamura]] is mistaken by his father to be the new chef (the Hiro of that time was a young boy). His mother orders eggs... but all Hiro knows how to make is [[TrademarkFavoriteFood waffles]]. She isn't mad at him.
* Mistress Ploppy in ''Series/{{Blackadder}} II'', who prepares whatever the condemned prisoners want for their final meal...provided they ask for sausages. Otherwise they tend to get a tiny bit disappointed.
* Ren from ''Series/EngineSentaiGoOnger'' can only make eggs.
* On ''Series/SweetGenius'', preparing the same kind of dessert for two rounds will earn chefs a tongue-lashing from the judge. This came up frequently in the first season where the Baked round was followed by the Chocolate round, and chefs tended to make chocolate cakes for both. To be a Sweet Genius, one must be versatile.
* During ''Series/TopGear'''s second road trip to Africa, Hammond rigged up a rather impressive kitchen in the back of his estate car. He then used it to cook nothing but baked beans for the duration of the trip.

[[folder: Theatre ]]
* In the opera ''Paul Bunyan'', the cooks Sam Sharkey and Ben Benny specialize (i.e., overspecialize) in soups and beans, respectively.

[[folder: Video Games ]]

* Minori in ''VisualNovel/BrassRestoration'' can make [[TrademarkFavoriteFood rice]], and [[LethalChef pure evil]].
* Somewhat of an example with LethalChef Raine in ''VideoGame/TalesOfSymphonia'', gameplay-mechanics-wise. Her cooking skill for almost all of the recipes in the game max out at two stars (for most characters, that only applies to a few recipes they happen to be "bad" at). However, her ability to cook spaghetti is better than that for the other recipes... that one maxes out at ''three'' stars. (And she starts out with one star on that recipe, instead of starting with zero stars for all the other recipes.)
** In the same game, Colette will add fruit to a good amount of her recipes (and the recipes she's best at are fruit-based). This is taken to the extreme in a skit in the sequel.
** From the same series but a different game, Repede from ''VideoGame/TalesOfVesperia'' takes this trope to its logical conclusion. Repede can be given any of the recipes to cook (of which there are a lot), and he even has a surprisingly low failure rate. Except regardless of if you have him make a sandwich, a sorbet, or hot pot, or anything else, all Repede can make... is dog food.
* Elmott of ''VideoGame/GranblueFantasy'' turns out to be an amazing cook as long as it involves grilling, roasting, barbecue, or other cooking methods that involve lots of fire.
* Flora of the ''VideoGame/HarvestMoon'' series is a LethalChef for anything that isn't curry. She knows it, hence it's all she cooks. Unfortunately for her, this has resulted in her boss/love interest Carter being sick to death of the stuff.
* Chef Shimi from ''VideoGame/PaperMarioTheThousandYearDoor'' can cook only with mushrooms, though this isn't much of a handicap in the ''Super Mario'' universe as he is stated to be a 5-star chef by the other [=NPCs=].
* ''VideoGame/MetalGearSolid'': Otacon's adopted daughter, Sunny, is incapable of cooking anything but eggs. Justified in that she also lives in an airplane and presumably subsists entirely on military styled rations and eggs from the three chickens on the plane. At one point, she attempts to cook a block of ramen in the same manner as fried eggs (by plopping it in a frying pan), and ends up setting a fire.
* ''VideoGame/{{Atelier Annie|Alchemists of Sera Island}}'' has Gillian, who attempts to put [[TrademarkFavoriteFood herbal health drinks]] in ''everything''. Unfortunately for the rest of the world, [[CordonBleughChef she and Melody are the only people who can even get near said herbal health drinks without gagging]]. [[spoiler: The reason for this is because when Gillian's father died, Gillian wouldn't eat anything until Melody offered a herbal health drink and drank it all down despite how awful it tasted. Gillian makes them because she insist that they'll help fight against sickness.]]
* Ms. Dungeon from ''VideoGame/{{Legasista}}'' is capable of making a variety of foodstuffs. The only problem is that the only ingredients to be found in the Ivy Tower are bean sprouts (both sentient and non-sentient), meaning that everything she makes tastes like bean sprouts, much to Alto's disgust.
* In ''VideoGame/TheSims2'', sims who botch using the [=ReNuYu=] Aspiration Changer end up with the "Grilled Cheese" aspiration. All their wants, fears, and dreams revolve around cooking, eating, and serving grilled cheese sandwiches. In addition, grilled cheese sandwiches normally require two skill points in Cooking and can only be cooked for lunch or dinner, but Grilled Cheese sims can prepare them at any time, without any points in Cooking.
* Forte from ''VideoGame/RuneFactory4'' is fine with salads and sashimi, but can't cook anything else to save her life. Her reasoning is that [[MartialArtsAndCrafts all her training as a knight has made her skilled with a blade]], but attempts involving pots and ovens don't translate so well.
* In ''VideoGame/LightningReturnsFinalFantasyXIII'' when a chef asks Lightning for help in preparing one of his recipes, she admits she's only good at grilling Behemoth steak over a campfire. Fortunately for her, it turns out the chef only needs her help to [[FetchQuest gather ingredients]] and not actually cook.
* Everyone who cooks in Mordavia in ''VideoGame/QuestForGloryIV'' has some kind of compulsion to put garlic in ''everything''. Lots and lots of garlic. [[spoiler: It might have something to do with [[VampiresHateGarlic the vampires]] running around, or that the creature that acts as the Dark One's symbol likes garlic.]]
* Brewster from the ''VideoGame/AnimalCrossing'' knows how to make ''really'' good coffee...and nothing else.
* The ''VideoGame/Persona5'' protagonist is a downplayed example; he can learn to make a damn good curry and coffee from his guardian, but that seems to be about it.
* ''Videogame/SunlessSea'': The Bandaged Poissonier is a special case; as the name tells, he's a ''magnificent'' cook when it comes to fish, especially the weird sorts of fish (and other monstrosities) that dwell in the Unterzee. In terms of other foodstuffs... it's not that he's incapable, as he still [[CordonBleughChef begrudgingly manages]], the problem's that he's ''unwilling'' to cook anything outside of fish, thinking it a waste of his talents. He's insulted ''kings'' over it, and preferred to abandon the country entirely rather than continue cooking for someone who'd clearly rather stuff themselves with inferior meals.
* ''VideoGame/StreetFighterIV'' gives us [[MaskedLuchador El Fuerte]], who is apparently very good when cooking Mexican Food. However, when he wants to experiment with any other kind of food, he turns into a CordonBleughChef. And he'll gladly prepare some food to any opponent he defeats...
* Papyrus from ''VideoGame/{{Undertale}}'' can only cook spaghetti, and even that is [[LethalChef barely edible]] (although he seems to be steadily, albeit very slowly, improving at it).
* Inverted in ''VideoGame/RPGShooterStarwish''. SupremeChef Johnny can make everything delicious ''except'' one thing: Eternal Swamp Gumboo.
* In ''VideoGame/XenobladeChronicles2'', Vess is only able to cook a particular type of dumpling, something Team Rex comments on when it's the only thing she serves them when inviting them for a meal. But Team Rex, her Driver Mabon and Mabon's kids all agree that the dumplings are exceptionally tasty, so it's not considered a particular handicap.

[[folder: Visual Novels ]]
* Tohno Shiki from ''VisualNovel/{{Tsukihime}}'' is good at making noodles.
* Inverted in ''VisualNovel/{{Kanon}}'' where Akiko can make everything, except a Special Jam which can file her under LethalChef.
* Haruka from ''VisualNovel/LittleBusters'' can make some quite nice egg dishes if she works hard on them, but is [[LethalChef pretty terrible]] at anything else. [[spoiler:This is because her twin sister Kanata told her that she was allergic to eggs when they were little, so Haruka focused on them as the one thing she could do that Kanata couldn't.]]
* When it's Rin's turn to cook in ''VisualNovel/FateStayNight'', she's careful to stick with the few dishes she's confident at making.

[[folder: Web Comics ]]
* The company chef in ''Webcomic/SchlockMercenary'' only makes things that involve whisking. Presumably because he has a whisk for a prosthesis.
* ''Webcomic/KarinDou4koma'': The only food Meguru can cook without burning to a crisp is karaage, but when she does make karaage it always turns out in massive quantities for some reason.
* Due to her dietary restrictions as a wolf, Florence Ambrose from ''Webcomic/{{Freefall}}'' can only work with meat or fish and very minimal seasoning. That said, [[http://freefall.purrsia.com/ff300/fv00236.htm she can prepare a venison dinner from roadkill]] in a GreasySpoon diner kitchen.

[[folder: Web Original ]]
* [[Wiki/SCPFoundation SCP]]-[[http://www.scp-wiki.net/scp-458 458]] is a pizza delivery box which, when handled, always contains a pizza of the handler's favorite style with their favorite toppings, within the realm of human comestibles.
* Shannon Blake of ''WebOriginal/TheWarComms'' is an excellent baker, but struggles with everything else. She's trying to change this.

[[folder: Western Animation ]]
* In ''[[WesternAnimation/MickeyMouseWorks Mickey Tries To Cook]]'', Minnie berates Mickey for only being able to make cheese, ham and tomato sandwiches, and thus that's all they ever eat at picnics. Mickey's attempts to learn how to cook something else ends in disaster.
* Arguably WesternAnimation/SpongeBobSquarePants. When he trades places with a chef for a fancy restaurant, his attempts at ''haute cuisine'' end up turning into Krabby Patties.
** An early episode showed him as having no idea what a sa-''[[AccentOnTheWrongSyllable lad]]'' was. When he learned, the concept of tomatoes and lettuce without a bun and patty freaked him out.
** Squidward is even worse. When [=SpongeBob=] went on a TenMinuteRetirement due to a trick from [[FatBastard Bubble Bass]], Squidward can't seem to cook anything right, even things that don't even need cooking. [[EpicFail Or things that are even food.]]
-->'''First Customer:''' Hey, he burnt my Krabby Patty.
-->'''Second Customer:''' He burnt my fries.
-->'''Third Customer:''' (drinks out of burnt milkshake) He burnt my shake.
** Also in "Hooky" after when [=SpongeBob=] goes to the "carnival" with Patrick and Squidward tries to hold the fort:
-->'''First Customer:''' P.U.! You call this food?
-->'''Second Customer:''' My sandwich tastes like a fried boot.
-->'''Third Customer:''' My sandwich '''''is''''' a fried boot! ''(holds up what appears to be a hiking boot covered in a crispy coating)''
* In ''WesternAnimation/ACharlieBrownThanksgiving'', Charlie Brown expresses (and demonstrates) an inability to make anything other than cold cereal "and maybe toast". He serves cold cereal again in ''WesternAnimation/RaceForYourLifeCharlieBrown'', (though apparently no one else even thought to ''bring'' food on their river-raft expedition).
* In an episode of ''WesternAnimation/TheVentureBrothers'', Sergeant Hatred takes over Hank's greasy spoon diner he's opened on the family compound, but admits that he only knows how to make scrambled eggs with ketchup.
* ''WesternAnimation/{{Doug}}'', and maybe by extension his entire family, has several books on making grilled cheese sandwiches. That suggests Doug can make mean cheese sandwiches.
* ''WesternAnimation/CourageTheCowardlyDog'': After Muriel's [[SpiritAdvisor Aunt Gertrude]] confides that vinegar is the secret ingredient to her famous raspberry jam, she begins putting it in ''every'' dish she makes thereafter (candy, pancakes, PB&J sandwiches, etcetera, etcetera). [[CordonBleughChef Her results]] [[ImpossiblyDeliciousFood vary]].
* ''WesternAnimation/EdEddNEddy'': Eddy often brags at others (especially when he's cooking) on how his omelets are the best and everyone needs to try them. For everything else, he's a mess at the kitchen, if the cooking class at school is any evidence.
* Bob Belcher from ''WesternAnimation/BobsBurgers'' makes good burgers - ''[[SupremeChef Fantastic]]'' [[SupremeChef burgers]], when it really matters. And of course, him being a One-Note Cook is justified by the fact that his restaurant is named...well, ''Bob's Burgers''. [[DownplayedTrope He's still decently competent at cooking other food]], and puts a lot of care and effort into things like Thanksgiving turkey - his excellent turkey has been a plot point in at least two episodes.
* ''WesternAnimation/TheLoudHouse'': The episode "Fed Up" reveals that Lynn Sr. makes the same seven dishes for dinner each night[[note]]Salisbury Steak Sundays, Meatball Mondays, Turkey Loaf Tuesdays, Wienerschnitzel Wednesdays, Goulash Thursdays, Fish Fry Fridays and Succotash Saturdays[[/note]], which he repeats every single week. However, it's justified in that [[RealityEnsues the Louds are on a budget and have to feed 13 different people]], so preparing large enough nutritious meals for everyone can be difficult. But in the end, even Lynn Sr. realizes that they should mix it up once in a while.

[[folder: Real Life ]]
* Although not that common in the U.S., many countries with a strong culture of cheap outside dining will have cooks who are extremely good at making things like tacos, pancakes, noodles, etc. These same cooks may also be absolute shit at cooking anything else, sometimes not even being able to cook their own meals aside from their specialty.
** Chef Duff from ''Series/AceOfCakes'' subverted this when he performed on ''Series/IronChef America'', and made excellent food. He still lost to Michael Symon, though.
** Bobby Flay gets accusations of this. While he's usually not abysmal at cooking outside of his element, his style heavily leans on usage of hot peppers - you can practically predict how close of a match he'll have in ''Series/IronChef'' or ''Throwdown'' based on how well the secret ingredient/proposed dish would work with spicy peppers thrown in.
* Since professional cooking encompasses such a wide variety, it is inevitable that there are certain cooks/chefs who are specialists. As such, while they may be excellent, even famed, at said specialization, they might not do so well outside of it.
* Certain Japanese sushi cooks are this. Becoming a cook in a sushi restaurant is a long procedure of learning (7 years, to be exact, and the first year of that is literally nothing but learning how to sharpen the knives), if wanting to be one that is allowed to serve [[MasochistsMeal blowfish]], they need to do a additional apprenticeship of several years. It happens that certain cooks are so specialized at sashimi, that they don't even know how to work a pan or how to cook rice themselves, having sous chefs that do that for them.
** It applies to an extent for many other restaurants in Japan, especially food stalls. Rather than cooking foods with a multitude of techniques, restaurants tend to specialize in one, and then tend to innovate around that. For example, a shop may only make yakitori (grilled chicken on skewers) but will have dozens of combinations of different seasonings and cuts of chicken (wing sections, thighs, breast, tenderloin, gizzards, livers, hearts, etc.) with which they make their mark.
