How to freshen rancid nuts? ›

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.

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.”

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.

There might be a risk associated with regularly eating fistfuls of oxidized nuts, though. Some emerging research suggests a potential link between long-term exposure to oxidized fats and negative health effects, like inflammation and increased cancer risk—but the connection is still unclear.

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.

Q: Do Nuts Expire? A: Nuts can't expire; however, they can change in taste or go rancid. Nuts contain much-unsaturated fat, an oil that makes nuts likely to go rancid.

"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.

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.

Some nuts are spoiled and can't be used as food, so adding them to the compost pile will get some use out of them. Give them the same driveway treatment as the empty shells to prevent having a grove of nut tree seedlings growing in your compost.

To refresh, it's best to preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) and spread the pistachios out on a baking sheet. Then, bake them for 10 minutes to bring them back to their crispy freshness.

How can you tell if nuts are stale? ›

Nuts smell sour and rancid and aren't quite pleasant. In terms of texture, stale nuts tend to feel softer and lose their trademark crunch when stale. Lastly, rancid nuts taste just like how they smell – sour and bitter.

Even if the bag's been opened, shelled nuts should last an entire year, and in-shell nuts will last about a year and a half. If you're going to use your nuts in the immediate future, it's fine to keep them in a cool, dark spot in your pantry.

Once the oils in nuts go bad and they become rancid, there's no fixing them.

Exposure to heat, light, oxygen and humidity can all make your nuts go rancid before you've gone through half the bag. Luckily, there's a much better option. Storing your nuts in the freezer is the best way to ensure your omega-3-packed walnuts give you all the heart- and brain-health benefits they are supposed to.

During soaking, it's normal to see a few nuts, seeds, or grains floating on the surface. These are possibly rancid. Discard them. It's not uncommon to have a lot of floaters.

Bake the nuts for 10 minutes. Halfway through the baking time, shake the pan and flip the nuts to ensure that they toast evenly. Remove the nuts from the oven and let them cool. Use the nuts in another recipe or have them as a snack!
