Storage tips
- Keep packaged nuts sealed in a cool, dry cupboard after opening to hit the window above. They do not need refrigerating.
- Refrigerating packaged nuts can stretch that to about 4 to 6 months if you prefer.
- Frozen, packaged nuts keep about 6 to 12 months, well past the window above.
- Reseal tightly and keep in a cool, dark, dry cupboard away from the stove.
- Move oils and whole-grain flours to the fridge or freezer to slow rancidity if you use them slowly.
- Decant opened dry goods into airtight containers to keep pests and moisture out.
How can you tell if packaged nuts have gone bad?
- A rancid, paint-like or crayon smell from anything with oil or fat (nuts, oils, whole-grain flours). Rancid fat is the most common failure here.
- Off flavors, stale texture or a musty smell.
