Yams, a.k.a sweet potatos.
Tried every which way to eat them- raw, baked, boiled, stuffed in a zucchini with cheese, candied even. Cannot get past the texture and taste, and gag almost every time.
This is no way shape or form contributing, but in their candied form, they kind of remind me of big boiled turds floating in some sort of viscous diarrheal sugar substance (that shot out of a toilet, and yes I've seen that episode of Dirty Jobs.) It's always a pity whenever someone puts the tiny white marshmallows on them, because it just makes it look even more like a nasty pan of dooky.
