I finally got around to making another batch. I had made one sometime in February and it turned out well, very normal. This time I had meant to split the batch into two bags: one straight-soy and the other a peanut/soy mix. When I went to the drawer to get the sandwich bags, there were none (note to self - check supplies BEFORE starting tempeh recipe), so I decided to combine the two in a larger storage bag. For reasons I don't completely understand, the mold didn't like the peanuts. The soy is all knitted together in fluffy white, but with isolated peanuts encapsulated within the soy/mold matrix. I really like peanut tempeh, so I need to figure this out. Maybe I'm undercooking them?
