Make Pizza (frozen) 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 — Keep frozen. For safety, cook as directed.

Don't

  • Leave it out on the counter while cooking or serving.
