Signs natural peanut butter has gone bad
- A sharp, rancid smell from the oil that floated to the top.
- A hard, dry layer at the bottom of the jar.
- Mould on the surface or around the rim.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store natural peanut butter
Natural peanut butter has no stabilisers, so the oil separates and the top layer turns rancid on a warm shelf. Refrigerate it after opening, and store the jar upside down so the oil redistributes back through it.
