How Can You Tell If Walnuts Are Bad?
You can tell if walnuts are bad by checking their appearance and smell. If they are discolored, shriveled, or have an unusual odor, they may have gone bad. You can also taste a small piece of walnut to determine if they have a rancid taste. It’s best to store walnuts in an airtight container, in a cool and dry place to extend their shelf life.
