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.

!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* Shana of ''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.
* Nerine of ''{{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.
* ''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.
* Saati in ''Manga/AILoveYou'', after learning to cook, can only make curry, even when she tries to make something else.
* This is practically a plot point of ''YakitateJapan''. Considering the sheer variety of bread Azuma can make, this might also fall under WhenAllYouHaveIsAHammer.
* 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.
* 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''.
* In ''{{Kannagi}}'', Tsugumi enjoys cooking. She can make eggs, vegetables, and [[BreadEggsBreadedEggs eggs]] ''[[BreadEggsBreadedEggs with]]'' [[BreadEggsBreadedEggs vegetables]].
* Nana's mother in ''NanaToKaoru'' can make rice omelette. ''Just'' rice omelette. It's still a step up from [[LethalChef her daughter]].
* Haruna in ''KoreWaZombieDesuKa'' can only make fried eggs... but they're ''[[ImpossiblyDeliciousFood really good]]'' fried eggs.
* 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]].
* 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.
* 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"
* Meiling from Manga/CardCaptorSakura is excellent at making Chinese food, but really bad at making any non-Chinese dishes... ''[[RunningGag specially]]'' [[RunningGag baking]].

* Calvin's Dad in ''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. Get the syrup out, will you?
* GreenArrow is legendary amongst the hero community in 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.
* [[SecretSix Catman]] only ever cooks eggs, though he once claimed he could "also make a mean slab of raw zebra haunch."

[[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.

[[/folder]]

[[folder: Film ]]

* The remake of ''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 ''{{Zathura}}'' can make one thing: water.
* Riggs in ''Film/LethalWeapon'' 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.

[[folder: Literature ]]

* In 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 should be noted that 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. 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 {{Wayside}} 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.

[[folder: Live Action TV ]]

* In ''{{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.)
* ''LoisAndClark'': "I can only make 4 things, and this is the only one without chocolate..."
* Charlie from ''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 ''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 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 ''{{Blackadder}} II'', who prepares whatever the condemned prisoners want for their final meal. As long as they want sausages.
* Ren from ''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]]

[[folder: Theatre ]]

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

[[/folder]]

[[folder: Video Games ]]

* Minori in the [[VideoGame game]] ''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.
* 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 he is stated to be a pretty good cook by [=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 ''TheSims 2'', 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 ''QuestForGloryIV'' has some kind of compulsion to put garlic in ''everything''. Lots and lots of garlic. [[spoiler: It might have something to do with 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.

[[/folder]]

[[folder: Visual Novels ]]

* Tohno Shiki from ''{{Tsukihime}}'' is good at making noodles.
* Inverted in ''{{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 ''FateStayNight'', she's careful to stick with the few dishes she's confident at making.

[[/folder]]

[[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/{{Karin-dou 4koma}}'': 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.

[[/folder]]

[[folder: Western Animation ]]

* In ''[[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 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 [[{{Jerkass}} a trick from Bubblebass]], 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:''' He burnt my fries!
-->'''Second Customer:''' He burnt my sandwich!
-->'''Third Customer:''' 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 ''[[{{Peanuts}} A Charlie Brown Thanksgiving]]'', Charlie Brown expresses (and demonstrates) an inability to make anything other than cold cereal "and maybe toast". He serves cold cereal again in ''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.
* ''{{Doug}}'', and maybe by extension his entire family, has several books on making grill 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 ''BobsBurgers'' makes good burgers - ''[[SupremeChef Fantastic]]'' [[SupremeChef burgers]], when it really matters. And of course, him being a OneNoteCook is justified by the fact that his restaurant is named...well, ''Bob's Burgers''.

[[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 ''AceOfCakes'' subverted this when he performed on ''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 ''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.
