Make Laitue Iceberg 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 leaves tightly in damp paper towels or freezer bags before freezing to maintain crispness.
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.
