"What was the fruit like? Unfortunately, no one can describe a taste. All I can say is that, compared with those fruits, the freshest grapefruit you've ever eaten was dull, and the juiciest orange was dry, and the most melting pear was hard and woody, and the sweetest wild strawberry was sour. And there were no seeds or stones, and no wasps. If you had once eaten that fruit, all the nicest things in this world would taste like medicines after it. But I can't describe it. You can't find out what it is like unless you can get to that country and taste it for yourself."

The fruit in Pan's Labyrinth looked delicious... considering Ofelia had been denied supper the night before (and rationed since long before that), you could almost forgive her for being totally Genre Blind...
God of Cookery has two dishes that qualify: Pissing Beef Balls and Sorrowful Rice. Both cause people to drift off into their imaginations while writhing about. (For those wondering, the former is a meat ball with juicy shrimp inside that squirts when bit into. The latter is just a well-made BBQ pork rice bowl.)
Sorrowful rice makes the judge burst into tears, as she knows that there will soon come a time when she -won't- be tasting this food in her mouth and the thought horrifies her. Or maybe it was the onion.
The fruit in "Goblin Market" by Christina Rossetti. Unfortunately it's also a metaphor for drugs. Or sex. Or... something. (Maybe temptation itself.) Once Laura eats some she loses the will to eat anything else, it's that delicious — but from that day on the goblin sellers of the fruit are invisible to her.

One Homer Price story is about "Ever-So-Much-More-So", an invisible powder which makes anything moreso of what it is.

Bertie: Good old Anatole, God's gift to the gastric juices. Many's the time that I have regretted I have but one stomach with which to enjoy his offerings.
Food from the titular Abbey in the Redwall series is normally described in such a manner as to make your mouth water. Eventually, a cookbook was printed, so now you can make your very own turnip'n'tater'n'beetroot pie! Redwall isn't everyone's taste in literature, but any writer who can make children want to eat food made mostly of vegetables has to be doing something right.
Aside from the page quote, C.S. Lewis used this trope in Perelandra with not one, but TWO Venusian fruits.
The bizarre short story "Biscuits of Glory," collected in one of Bruce Coville's anthologies of children's stories, features biscuits that are "heavenly" in a near-literal sense. In a normal person, this causes levitation. When given to a ghost, it "feels like it went to heaven," and is exorcised. Of note is that this is ultimately a negative effect, because nothing else can compare to the taste of the biscuits.
Mentioned briefly in A Wrinkle in Time. When Meg is recuperating from her brush with IT among Aunt Beast's people, the food that Aunt Beast gives her is described as "incredibly delicious" — just one more way in which aliens are superior to humans.
A softer version of the trope is played with earlier; Meg, Calvin, and Charles Wallace are offered a meal on Camazotz by the Man with Red Eyes. Meg and Calvin happily enjoy their delicious meal, while Charles Wallace complains that all he can taste is sand. It turns out it's a form of mind control. Since the Man with Red Eyes can get past Meg and Calvin's mental defenses, he is able to convince them the meal is good. Since Charles Wallace unknowingly puts up more resistance to the control, he cannot be convinced.
In the Discworld novel Thief of Time, newly incarnate entities known as the Auditors are exposed to chocolate for the first time; the experience is so overpowering that it physically kills them. Though this is sort of an inversion; the chocolate is ordinary chocolate. The Auditors designed their bodies under the assumption that more sensitive taste buds would allow them greater analytic accuracy, but meant they could not handle strong tastes such as from chocolate.
A major plot point in one of Bone Chiller's novels (a series of children's horror fiction novels similar to Goosebumps). A new lunch lady makes food so delicious that all the students and teachers flock to the cafeteria every day to get a taste of her meals, and even fighting over them. It's so good that the main character cannot bear to eat anything other than her cooking, comparing his cornflakes he ate for breakfast to sawdust. However, over a series of strange events the he realizes that the lunch lady is actually a giant insect who implants eggs in her cooking so that they will incubate in the hapless residents, controlling their movements until they eventually hatch and discard their hosts' bodies. The main character manages to bring the bug lady down with the help of a fellow student (who was allergic to outside food and had to bring her own lunch to school).

In Doorways in the Sand by Roger Zelazny, mirror-reversed bourbon is described this way.

The wine which the angel Islington serves to Richard and Door in Neverwhere is described in terms of this trope.
Pity that it causes a horrible hangover afterwards. Possibly a hint that Islington isn't as nice as he seems.
In Spider Robinson's Mirror Mirror, Off the Wall Robert Trebor gives Callahan a case of liqueur in exchange for a case of rotgut. Jake Stonebender called Trebor's drink "The Wonderbooze", saying that "it felt to the mouth, I imagine, the way a velvet pillow must feel to the cheek. And it kicked like a Rockette. It ennobled the mouth." Trebor, it turns out, is from a mirror universe with a reversed metabolism; what tastes terrible to us would taste wonderful to him and vice versa.

In Charlie and the Chocolate Factory, Willy Wonka's confections are so tasty and wildly imaginative that rival candymakers sent spies into his factory to steal the recipes for them. He responded by closing it down, and when it finally was up and running again, no one could figure out how it was possible — no workers were ever seen going in or out and Wonka himself was now a Reclusive Artist. Thus, when the news breaks that a contest to win a trip into the factory has been launched, it becomes an international obsession. The 2013 stage musical adaptation gives much of the expository song "The Amazing Fantastical History of Mr. Willy Wonka" over to discussion of just what Serious Business his treats were even before he became a recluse:
From all around the world they called on Mr. Wonka
Kings and queens and presidents
Even down in Rome the Pope left home
And in the fact'ry took up residence
Dalai Lamas and their mamas
Had such episodes and dramas!
Even Gandhi got himself into a brawl
In Star Trek: New Frontier the Beings (true to their Greek god heritage; see below) have the legendary ambrosia.

One episode of QI discussed how it took over three hundred years from its discovery for a specimen of the Giant Tortoise to be presented to the British Museum, simply because people kept eating them before the ship could reach its destination.

Unfortunately, they're a protected species now...

(The mercenaries choose the cookies over the orc chieftain's offer of allowing them a portion of the loot and their pick of the women of the conquered territory for not trying to stop them.) Oh, and you know how Nodwick is a Chew Toy for whom even his hundreds of deaths is no escape from constant mistreatment at the hands of Artax and Yeagar, and whatever monsters they encounter? He's still a lucky bastard because when Piffany makes her cookies he gets to lick the bowl.

He can't stop eating it, even long enough to save his friends. When Leela frees him from it by dumping it down the sewer, Fry tries to chew his own arms off to follow it.

Despite a stern voice that bluntly warns anyone who enters the room of the danger, it appears that dogs simply cannot resist it. (The numerous dog skeletons surrounding it seem to confirm this.) Courage falls under its spell too, but saves himself and the other dog by somehow managing to pick the giant bone up and carry it with him.
