Signs peanuts have gone bad
- Rancid or stale smell — nuts, seeds, and nut butters turn over time.
- Mould, sliminess, or an off texture.
- Loss of crispness or an unusual taste.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store peanuts
Keep dry snacks airtight in a cool, dark pantry. Nuts, seeds, and nut butters keep far longer in the fridge or freezer because their oils go rancid at room temperature. Fresh herbs and tofu belong in the fridge.
