How to rejuvenate stale nuts? ›

They do go stale and lose their luster and they need to be brought back to life (you know you have a can of them somewhere; don't throw them away!). Toss roasted nuts in a bit of olive oil, sprinkle with flake salt and Air Fry at 400F for 4-minutes (no preheat). Hello co*cktail Snack!

If a nut is only slightly stale, says Kanney, it can usually still be toasted to revive some of its previous glory and (crunch). However, Kanney says, “If a nut has spoiled or gone rancid, recognizable by a sour or bitter flavor, the nut is no longer good and should be thrown away.”

Just toasting them in a dry pan or oven should be enough to revive them, but they'll also go in any recipe that requires nuts. We got through most of ours by toasting them with spices, to eat as nibbles or to add crunch to soups, stews and salads. I also made a vivid green marzipan with some of the pistachios.

Microwave the nuts at one-minute intervals, stirring in between until evenly toasted and golden. Depending on the amount of nuts you're working with, this takes between three and eight minutes or so, and the results are more even and better-flavored than anything you can get out of a skillet or toaster oven.

“If a nut is really oxidized, I guarantee you you're not going to get it past your mouth because it just tastes so awful,” says Schaich. But if you do, for some reason, eating the occasional spoiled nut is “no big deal,” because we have enzymes in our stomachs that can essentially incinerate the oxidation byproducts.

"Nuts have a wide range of fat contents," says LaMarita. Almonds, walnuts, and pistachios are lower in fat, so they'll generally last longer than nuts higher in fat, like macadamia nuts, pine nuts, cashews, and Brazil nuts, all of which will go rancid quicker, says LaMarita.

Avoid storing nuts near heat sources like stoves, ovens, or direct sunlight. Instead, choose a cool and dark storage location to extend their shelf life.

Exposure to heat, light, oxygen and humidity can all make your nuts go rancid before you've gone through half the bag.

To make rancid walnuts tasty again, a "chemical engineer" (consulted for this purpose) advises to soak the rancid walnuts in milk or other emulsive ingredient which is then rinsed off with hot water, and the nuts gently dried and roasted with sea salt.

Are rancid nuts bad for squirrels? ›

But if the peanuts are stale or if you see any sign of mold or discoloration, then do not give them to the squirrels. The same idea goes for corn. Although many people leave dried corn cobs out for squirrels, it can actually be harmful to them. The corn can get moldy, just like peanut shells.

Spread the stale snacks out on a cookie sheet and place in a 350o F oven. Let them bake for about 10 minutes and then remove from the oven and let cool completely. Once cooled the snacks should be crispy and refreshed. You can use this method with fresh nuts like almonds, peanuts, walnuts, etc.

How it works: Place the nuts in cold, dry skillet over medium heat and toast them, tossing frequently, until browned in spots and fragrant. Then immediately transfer the nuts to a plate or bowl.

Spoilage is accelerated even more in the presence of light, oxygen, and heat. Storing nuts (and seeds) in the fridge or freezer limits their exposure to all three of these, and will result in your nuts tasting less bitter and more flavorful for a longer period of time.

Soak your nuts and seeds anywhere from 20 minutes to 2 or 3 hours, or even overnight in the refrigerator. In general, harder nuts will take longer to soften. If your recipe calls for soaked nuts or seeds and you are low on time, try to squeeze in 20 minutes minimum, or just do a really good job rinsing them.
