The Bracha on onions and garlic eaten raw is shehakol since its not the usual way to eat onions or garlic raw. Do we say that jalapeños are also shehakol when eaten raw according to the same logic?
I have a friend whose wife is from Mexico. He once told me that in a shiur (class) given in Spanish by Rav Vaia he said that for them the bracha is ha'adama, since they are used to very spicy foods, but for most people it would be shehakol. The thing is, I heard this secondhand, and I don't know whether he was joking or giving a psak.
