Storing & preserving

Refrigerate ripe fruit; ripen firm fruit at room temperature.

  • Freeze: Freezes well raw; spread on a tray first so pieces stay loose.
  • Preserve: Make jam or water-bath can high-acid fruit.
  • Dry: Dehydrate or air-dry, then store airtight away from light.

General home-preservation guidance — for tested processing times and safety, follow the National Center for Home Food Preservation.
