The things I like in chocolate
Just chocolate
Nuts - Almonds and Cashews especially
A little more cocoa (not so much that it is bitter chocolate)
Cake/Pastry
Things I don't mind in chocolate
Peanuts (if it is Snicker bar)
Raisins
Wafer
Biscuit
Liqueur
Nougat
Things that should not be in chocolate
Caramel
Mint (makes it taste like chocolate-toothpaste combo)
Caramel crystals
One of those strawberry/orange pasty stuffing (*gak* That's worse than mint!)
