When I was a kid, my grandmother had some trick that caused her bland spaghetti (possibly with some oils and stuff, but mostly things that weren't visible after it was prepared) to be the best food that I knew of. If not superstimuli, then close to it.

Unfortunately she's no longer alive, and she never passed the trick on to anyone else, so I can't say whether I would get the same pleasure out of it as an adult.
