I am so with Melissa on marshmallow peeps. Also on my list: Donuts. Capers. Chardonnay. Cocktail weenies. Aplets & Cotlets which, growing up in Washington State, I always got as Christmas presents. Lemon-flavored desserts (especially any sort of mousse, yuck). Jello, especially the way my grandma — God rest her soul — used to make it (with grapes inside).
Despite my long list of foods I despise, I’ll try pretty much anything once, and I tend to like strong and/or odd flavors. The only food that I have ever absolutely refused to eat was bull penis in Tunisia. It was (surprisingly) small and spongy and pink and in red sauce, and I just could not do it. You can kind of see it in this picture.
What do you hate to eat?
