We all know not to judge a book by its cover, but what about food? Chances are, if something smells and looks repulsive, it'll taste just as bad. After all, how could that plate of green eggs be anything other than rotten, or that bowl of murky, gray mush be anything other than nauseating? This is especially true if we're expected to taste something that isn't often eaten in our culture, such as a middle-class American being fed a bat—or a normal human being exposed to an Alien Lunch. In many cases, a bad smell, texture, or appearance will be an immediate sign that the food should not be eaten, for our own safety. After all, who really wants to eat a Mess on a Plate?
And sometimes, our senses will be lying to us. That bowl of bat wings will be the best thing the American has ever tasted, that gray mush will turn out to be a very rare and delicious type of soup, and someone will discover that they really do like green eggs and ham. Characters who decide to be open-minded will be rewarded with a delicious meal and may be pleasantly surprised that someone they thought was a Lethal Chef is actually a skilled chef whose presentation just needs some work. They may learn An Aesop about trying new things while they're at it.
Like I Do Not Like Green Eggs and Ham (which covers more than just food), the character carries some preconceived notion that they will hate the thing, but they eventually try it and realize they were wrong. In this case, though, the thing genuinely doesn't look appetizing to begin with.
May overlap with Foreign Queasine and Cordon Bleugh Chef, if the prepared food is gross-looking to someone, but they end up liking it after they try it. The food may Taste Like Chicken. See also If It Tastes Bad, It Must Be Good for You, where a character makes assumptions about food based on its taste rather than appearance.
- My Girlfriend Is A Shobitch: Subverted when Akiho is trying to complete a cooking assignment in class to impress Haruka (her boyfriend) and makes a horrific-looking mess.

- One episode of the Pokémon anime in the Advanced Generation series is about this. The main characters come across two competing restaurants whose chefs are Pokémon, a Sneasel and a Mr. Mime.

Nino makes a delectable dish that shows she clearly knows her way around a kitchen, while Miku makes a very haphazard and ugly dish made from cooked rice, ketchup, and some kind of sauce. However, when Negi tries both of them, he says that they're both equally good. Ultimately played with though, since Negi had been previously established as someone too poor to be picky about his tastes, so how good Miko's dish actually was is left in question. Still, Miku swoons when Negi compliments her cooking and later makes an effort to improve in order to win him over.
- In Kill la Kill, Sukuyo Mankanshoku's croquettes are made of weird, unidentifiable ingredients and, in one scene, have something still moving around in them when served. Despite this, her husband, children and Ryuuko find them delicious.
- Calvin and Hobbes:
- In a strip:
Calvin: [looks at the Alien Lunch dinner in disgust, takes a bite, and has a Wild Take reaction]
Calvin's mother: Oh, knock it off, Calvin. It's hamburger casserole. There's not a thing in there you don't like.
Calvin: This is hamburger? [takes another bite] Hmm... This bit wasn't so bad, for some reason. I was able to choke it down, anyway. My stomach is still cramping up, but the pains aren't as sharp any more. The secret is to suppress the gag reflex. After I swallow it, I can stand it.
Calvin's mother: Good. I'm glad this is such a hit.
- On some occasions, Calvin's mom jokes that she's made something over-the-top disgusting for dinner, like fried monkey heads or spider pie. Invariably, this intrigues Calvin enough that he tries it with an open mind and actually likes it—but Calvin's dad gets grossed out and can't finish his meal.

- Warhammer 40,000: In Death or Glory, the breakfast Jurgen makes one day is described as "gray and lumpy". It smells appetizing, and Cain comments that after eating the whatever-it-was, he felt ready for anything the day might hold, so it must have tasted good.
- A few episodes of Iron Chef featured chefs who made some questionable-looking but delicious dishes. The Japanese series featured an ice cream episode with the crab ice cream described as "not at all fishy and surprisingly good". Chefs had, over a number of episodes, attempted some kind of fish ice cream, which the tasting panel hated. Finally, Stephanie Izard, challenged with yellowfin tuna, dared make an ice cream with it, and she finally pulled off a fish ice cream that worked. The American show had beer sherbet in the Battle Oktoberfest (featuring Bavarian ingredients). The caramelized bacon on top of the ice cream threw people off, but the judges loved it.

Lister: The trick is, you've got to eat it before the bread dissolves...

- In an episode of My Little Pony: Friendship Is Magic, the buffalo served Rainbow Dash and Pinkie Pie bowls of vile-looking green mush, perhaps a stew. Dash is revulsed at the look of it.

The man finally has an emotional breakdown, so the woman samples the dish out of sympathy, but she finds it to be tasty, much to his surprise. The more they eat, the more animalistic they become. They finish the dish and eat up the plates, silverware, and even the table.
- A pomegranate's inside can look slightly visceral and bloody to sensitive people. You ignore the bitter pulp, and pick out and eat or juice the seeds. The seeds are very juicy and very sweet, and the flavor is comparable to red grapes or cherries.
