How to Store Nuts
Nuts are pricey these days, so you need to make sure you're storing them correctly for lasting freshness. Glass, plastic containers and our heavy, reclosable ziplock bags are good for storage. Metallic containers, light, moisture and heat will all conspire to spoil nuts more quickly. Light can cause the nuts to go rancid at a quicker pace, so you're better off storing them in a cabinet. Nuts also have a tendency to absorb odors from their immediate environment, so keeping them separate from other foods is wise. We have learned not to pack mints in the same gift packs with nuts!
Certain nuts will expire more quickly than others. Peanuts, pecans and walnuts are some of the first to go, with almonds and cashews being the most hardy. Nuts become chewy and soggy as they begin to turn and will eventually become rancid. To freshen the nuts you can bake them in the oven on 350 degrees for ten minutes.
