I know I going against the grain on this one(no pun intended), but I make an almond scented bar with almonds in the soap. I run the almonds through the magic bullet so the pieces are super small. I made the batch a year ago and we just used the last bar about a month ago. It was for personal use because I was worried about the nuts going rancid, but that did not happen. My bf has been after me to make him another batch because he loved it so much. No mold, not too rough on the skin, and it did not go rancid. Sheli
