Make Cashewkerne Naturbelassen last the full window
Do
- Refrigerate promptly after each use, at 5°C / 40°F or below.
- Use a clean utensil every time you take a portion.
- Keep it sealed — the original lid or an airtight container.
- Freeze it before the window closes if you will not finish it — Store in an airtight, freezer-safe bag or container for long-term preservation.
Don't
- Leave it out on the counter while cooking or serving.
- Double-dip or return unused portions to the container.
- Store it in the fridge door if you open the fridge often — it is the warmest spot.
- Taste it to "test" safety. If in doubt, throw it out.

Where this guidance comes from
The Cashewkerne Naturbelassen window blends official US food-safety guidance with typical manufacturer opened-storage instructions. The label on your specific product always wins if it is stricter.
Storage note
Both the UK and US generally treat dry, opened nuts as having a similar shelf life, primarily limited by rancidity rather than immediate bacterial danger.
Check before eating
Look
The nuts may develop a slightly dull or discolored appearance, but this is often cosmetic.
Smell
A noticeable, sharp, or 'off' odor indicates rancidity, which is the primary spoilage concern.
Texture
The texture should remain crunchy; signs of mold or clumping suggest significant spoilage.
Freezing
Yes. Store in an airtight, freezer-safe bag or container for long-term preservation.
