Make Biscuits 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.
- Skip the freezer for this one — Not suitable for freezing; freezing can compromise the biscuit's texture and structure.
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.

The Biscuits 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.

Both regions recommend keeping biscuits dry, but the US guidance allows for a slightly longer period due to packaging variations.
