I like putting peanut flavor in my sauces and wanted to make a big batch of crushed and pulverized peanuts.
I was wondering how long I could keep these, before they went bad.
Best Answer
There are no safety concerns here. Baked and shelled peanuts are shelf stable, no matter if they are pulverized or not. Just smell before each use and discard once it turns rancid.
