The brachot site states:
Fruits and vegetables which are normally eaten cooked but not raw – would receive their ideal bracha (Ho’eitz or Ho’adomo) when cooked, and only shehakol when eaten raw.
Examples would be: quince, and peanuts. (almost all peanuts are roasted, either in or out of the shell, and therefore raw peanuts would be shehakol.)
I like to eat raw sesame seeds. However, as far as I know, sesame seeds are usually eaten when it is used as a topping on bread, pastries or borekas, etc. Offhand, I don't think that it is customary for people to eat raw sesame seeds in the U.S., but I'm not sure if this is common or not.
What bracha should I be making - ha'etz or shehakol?
