Nuts are prized in the kitchen for their flavor, texture, and oils, but those oils can trip you up — as good as they are fresh, nuts can be shiver-making horrible when they go rancid — and they can go rancid quickly. Make sure you buy your nuts from a supplier who has a good turnover, and when you get them home, if you’re not going to be using them soon, pack them airtight and store them in the freezer. Always taste a nut or two from the package before tossing them into a recipe — it could save your dinner.
