Orgasmically Delicious

Okay, so Alice and Bob likes pie. In fact, it's her Trademark Favorite Food. Thing is, when she eats it, she seems to derive a more-than-culinary pleasure from the experience.

For her, this food is Orgasmically Delicious.

If watching Alice eat said food is Fetish Fuel, then it overlaps with Erotic Eating. If this food actually boosts the character's performance, then it overlaps with Power-Up Food. If it has this effect on everybody, a Supreme Chef probably prepared it. If Bob really likes Alice, he may give her some in hopes that she will return his affection.

May be the result of character's favorite food becoming Flanderized. Could be Justified if the character is starving.

Can also apply to drinks.

See Establishing an Unreachable Baseline when a particular version of the dish resets the diner's "minimum acceptable".

No real life examples, please; this is All The Tropes, not Tropes After Dark.

In the Harem Comedy Yuragi-sou no Yuuna-san, male lead Kogarashi has learned a wide variety of skills, which definitely includes his cooking; it often strikes the lucky ladies who taste his food in this way. (They're not actually naked; that's just another aspect of their reaction.) The "little girl" responding to the sweet bean jelly is actually over a thousand years old, so she'd have plenty of experience of quality eating, but the pleasure still overwhelms her. One girl said a dish Kogarashi had prepared was so good, not just in taste but in appearance, that it seemed as if it must have been made by a deity rather than a human.
