Make Petit Crisp 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 — Wrap tightly in plastic wrap or foil and freeze in an airtight container for up to 3 months.
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 Petit Crisp 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
UK guidance is generally more conservative for baked goods, recommending disposal after 3 days. US guidelines allow slightly longer, but refrigeration is key in both regions.
