Bertie Botts Every Flavour Beans were a popular sweet in the wizarding world. They were invented by Bertie
Bott, and they were almost identical to Muggle jelly beans,
except that they came in every flavor imaginable. There was also no way
to know for sure what flavor a bean was without eating it, though you could guess based on its color.
There were common flavors like chocolate, peppermint, and marmalade,
as well as more unusual flavors like spinach, liver, and tripe. There were also flavors like grass, farm dirt, vomit, earwax, paper, and
bogeys that weren't actually foods.
