@tinker I'm hoping you are using roasted peanuts that have been heated up enough to kill #aflatoxin. Also, make sure you clean your grinder on a regular basis. (I was just reminded of aflatoxin a few months ago, since I'm attempting to grow my own peanuts again).
"Making peanut butter at home can mitigate the mold by soaking, sprouting, de-hulling, and roasting your peanuts before using them."
