Okay then. I'll begin. I dislike anything in the "gruel" department. I know it's very non-Anglo of me but I despise porridge, cornmeal, polenta and Cream of Wheat. It triggers a rather untriggerable gag reflex. And to me it's also what it must be like to eat warmed wallpaper paste. Bleeeech. I don't particularly like veal either unless it's been "doctored" rather heavily with seasoning and wine. Beyond that I don't truly dislike anything except for overly spicey foods.
