- 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 roasted sunflower seeds 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.
