We attempted to make peanut butter using the homogenizing plate and got peanut powder (didn't taste real great either). . . read your FAQ about almonds getting powdered in the Green Life as well. Should we buy roasted peanuts (we had used raw) or did we do something else wrong?

Thats tough.. the problem is that most raw nuts dont contain enough oil. When nuts are roasted, I think it brings out more oil. Try some roasted peanuts, that should work.. if not, take some peanut oil, and add it to the peanut powder (a little at a time), and it will turn into more of a "butter" consistency.
