What that means

Plan to finish it this week.

Use this as a planning window, then check the real-world spoilage signs below before eating.

Make Nata Leve 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 — Freeze in an airtight container for up to three months for best quality.

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.
