I think maybe Berite Bott's Every Falvour Beans, simply because of the randomness of the flavours 당신 can get! I can just imagine sitting there with my 프렌즈 and how much fun we'd have daring each other to try the 다음 one. There's also those sweets that made Ron, Neville, Harry and this other boy (who I can't remember) act like animals, which would be hilarious if it existed! I also like the 마법에 걸린 사랑 초콜릿 frogs. Though, I'd probably end up not wanting to eat it if it was moving about like it was alive! :)
