Freeze Nuts to Preserve Freshness
Nuts purchased in bulk (like at health food stores) are usually fresher and cheaper than those sold in small bags, but it can be hard to use them all up before they go rancid or stale. Here's a simple way to preserve the freshness of nuts for a long period of time.
To keep the nuts from going stale, store them in an airtight jar in the freezer. You'll always have plenty of fresh nuts on hand—they defrost in minutes and you can get out the exact amount you need.
