I am allergic to Brazil nuts. All other nuts are OK for me but I don't like them. Peanuts, IMO, don't belong anywhere near chocolate. Hazelnuts are really vile. Almonds are just about OK. But Brazils - well, when I was six, someone gave me some chocolate with Brazil nuts in and immediately my tongue and throat became swollen and my skin produced huge red lumps. I couldn't breathe - it was very scary.
