Not roasting :)
The outer shell gets dry, hard and crispy. But when the peanut is cracked open to eat, it is still raw. Some are kinda the same consistency as if I were eating a fresh pea, others are a little mushier, and then there are the occasional few that are similar, but not exactly the same as a store bought peanut. Ive done the 350F 20 minutes with and with out oil. Some I left for a longer period of time, but the outer shell just got darker , the inside didn't change much at all.
I guess being a New Yorker, I should stick to Bagels and Pizza, and leave the peanuts for you guys in the south
