The culinary equivalent of RubberForeheadAliens. Alien cuisine has a suspicious tendency to look like Earth food ripped from its terrestrial context and subjected to food colouring -- leading to things like green egg yolks, glow-in-the-dark yellow sauces, obsidian berries, and blue meat.

This rises from production considerations, of course. It takes time and energy to think up genuinely alien foodstuffs, and money to fabricate them -- and in the end, the viewer might not even realize it's supposed to be food. By keeping the forms the same, creators can make it clear that a pudding is the ambassador's dinner and not, say, [[BizarreSexualDimorphism his wife]]; by shifting the palette, they retain a sense of otherworldliness.

The more humanoid the aliens in question, the more plausible this trope becomes. Green-skinned people who are shaped just like humans might very well share a biome with red-skinned vegetables that are shaped just like asparagus.

[[folder:Anime and Manga]]
* ''Anime/TenchiMuyo'' has alien beef bowls.

[[folder:Film]]
* ''StarWars'' had [[MemeticMutation BLUE MILK!]]
* ''MoronsFromOuterSpace'' mentioned a space beer that was green.

* Franchise/StarTrek is fond of this:
** [[Series/StarTrekTheOriginalSeries Romulan Ale]] is blue.
** [[Series/StarTrekTheNextGeneration TNG]] Gave us the Klingon specialities ''[[EatThat Gagh]]'' and ''[[GargleBlaster Bloodwine]]''
** Parodied in Magazine/{{MAD}}'s spoof of ''[[Film/StarTrekIITheWrathOfKhan The Wrath of Khan]]'', which mentions "green wine" and "brown wine".
*** One episode in the original series featured the drinking of something that (when one of the characters drinking it was prompted) was identified as "Well, it's... uh... it's green." Of course, this was after several bottles of alcohol -- presumably it has an actual name.
*** [[Series/StarTrekTheNextGeneration TNG]] has a CallBack to this line when Data can find no better descriptor for an unknown alcoholic drink from Guinan's stash, later identified by Picard as Aldebaran whiskey. Presumably not the same drink as above, as Scotty, who consumed both, did not recognize the second. (That, or he was too drunk the last time to remember.)
* Shows up on occasion in ''Series/StargateSG1''. Lampshaded in the parody episode "Wormhole X-Treme!": "You think they have ''apples'' on an alien planet?... Look, get some kiwis, and spray-paint them red." Subverted by the little FoodPills the Asgard eat.
* ''Series/BabylonFive'' has mostly normal food, but sometimes shows off alien food as well... and has at least one of the characters fail spectacularly in preparing it for another alien. This was justified in that the two species have only slightly different senses of taste, so when he spiced it to his own taste it tasted horrible to them.
** A memorable inversion occurs when G'Kar serves a fellow Narn Swedish meatballs because it resembles and tastes like a native dish called breen. G'Kar then mentions that every alien species has inexplicably invented a dish resembling Swedish meatballs.
* Showed up a lot in ''Series/{{Farscape}}'' and also included non-human-looking utensils. According to the commentaries, sometimes they just used Asian foods that would look alien to the intended American audience.

* A cutscene in the futuristic [=PlayStation=] FPS ''Disruptor'' showed the main character eating recolored macaroni and cheese, which looks extremely disgusting as [[{{Squick}} its greenish-blue tint makes it seem as though it had been fished out of a portable toilet.]]

[[folder:Western Animation]]
* In ''LiloAndStitch,'' Jumba and Pleakly attempt to bait Stitch with what appears to be an ordinary chicken drumstick... which is also bright green, and covered in purple spots.
* Razer eats a grey steak in ''GreenLanternTheAnimatedSeries''. Bonus points for eating it exactly like you would eat a steak.
* A downplayed example in an episode of "Arthur" featuring George's mother being puzzled by a purple object she picks up in the grocery store that turns out to be purple okra, which Sue Ellen's father claims is delicious (so this would be PaletteSwappedAlienFood with Alien just meaning from another country on Earth).

[[folder:Real Life]]
* Some genera of food plants have a relatively broad range of phenotype worldwide, but one particular form is dominant in a given region. And food preparation can vary in unexpected ways as well. So traveling to a different country, or just eating with people of a different ethnicity, may seem like this.
** Probably the most famous case of this is the carrot, which originally came in a variety of colors ranging from white to red to purple. Orange carrots only became widespread after Dutch farmers during and after the EightyYearsWar bred their carrots that way to proclaim their support for the House of Orange (and thus Dutch nationalism). For whatever reason, the color spread and stuck.
* And it is hardly unheard-of for chicken eggs to have moderately dark, greenish yolks, though commercially produced eggs in some countries tend to a brighter yellow. There are also breeds of chicken that consistently lay eggs with green shells. There are also blue, pink, gray, and probably others.
* Various traditional preservation methods and processing techniques leave food looking, smelling and sometimes even tasting distinctly inedible because food only had to ''last''. This is in contrast with modern food technology, which aims to modify taste and shelf life with as little cosmetic change as possible even if artificial means must be used. Corning beef will turn it an unappetizing gray color, but saltpetre can be added to the brine to preserve its reddish-pink color.
