I seem to be odd within my family.
My least favorite food (or 2nd, but the other one is less universal within) black eyed peas. Dont get it, it taste like mud with less flavor (with a hint of paper taste, dont ask how i know how mud and paper taste). I have to wash down.
Beans, especially, is also a family favorite, they are less repulsive than above, but still cant eat.
Note: the other hated food i didnt mention is coconut. The taste is awful but survivable but in combo with the texture, i end up in chew and heave mode getting it down.
