Food items you enjoy in only very limited quantities or amounts?
You know the case ... the first bite is pure heaven, the second not so much, the third becomes absolutely revolting.
In other words, foods for you that have very very steep diminishing marginal utility curves.
For me, it's ...
Luckily, my marginal utility curve for the following foods only goes down after I've had a face-full, not just a few bites. But I know where the OP's coming from.
Once a year, I make a liverwurst and onion sandwich on buttered/mustarded black bread with an obscene amount of onions.
Once a year, I buy a can of Underwood Deviled Chicken and make a spread with cream cheese and chives. Spread it on Town House or Triscuit. Top with chopped olive/pimiento.
Once a year, (I'm usually drunk) I buy a jar of marshmallow Fluff, some Skippy peanut butter and Arnold's Brick Oven White bread and make Fluffer-nutter sandwiches until I get sick.
These days I buy Italian pastries only 2-3 times a year. Sfogliadelle, in particular, gets "old" with me very fast, but I *must* have it at least a few times a year.
I lerrrrrve liverwurst (or Braunschweiger) on whole kernel rye with red onion and mayo, YUM.
I eat the liverwurst often, but bread (and all starches and sweets) very rarely.
Once a year I have a small cup of premium cherry vanilla ice cream, and less than once per year I buy a chocolate dipped almond horn.
It's probably a good thing to eat the fluffernutter til you get sick; keeps it down to annual, right? ;-)
Halvah. A piece about the size of a marshmallow is plenty for me. And those sugared pieces of coconut sold on the street. I always eat half and throw the rest away, because enough with the sugared coconut already. It's also really hard to chew.
Umeboshi. I get cravings for these, but I only want one or two. They are much too salty to eat a lot of, and I only want them once in a while.
Kraft Dinner. With a tiny amount of ketchup. It is so gross, but so good. I want it every once in a while, but after the first few bites which are amazing, I have for force myself to finish the rest of it.
Sweet potatoes/yams, 2 bites, done. Even french fried ones.
Caramels, 1 that's it!
Jalepeno poppers, after just 1 they seem disgustingly mealy.
RyKrisp, love the first peice, no more.
