TEXT B

Freezing

Freezing is a good option for fruits you like adding to smoothies or baked goods (bananas, berries, cherries, etc.) and those that aren't suitable for canning. Vegetables such as broccoli, beans, carrots, peas, and corn freeze well, too. Freezing is quick and requires little in the way of equipment or skill, but frozen foods don't last as long as canned foods. Plus, some integrity is lost (foods darken or develop a mushy texture) after freezing.

Supplies you will need:

  • Flat baking sheets (or similar containers) that fit into your freezer

  • Freezer bags or reusable containers that have tight-fitting lids

  • Permanent marker and labeling supplies

  • The foods you are freezing

How to do it: Many vegetables will require a short blanching (a short boil) before freezing. Beyond that, the method of freezing and storing vegetables is the same as that of fruit (below).

  1. Wash, core, and skin (if needed) your fruit. Cut fruit into slices or chunks, if desired.

  2. If you are concerned about browning, you can soak the fruit in water with a bit of lemon juice; commercially made agents are available for this purpose, too.

  3. Lay prepared fruit on several baking sheets in a single layer. Make sure your fruit is patted dry or unnecessary ice crystals will form.

  4. Place baking sheets into the freezer, making sure no fruit is touching, for several hours.

  5. Once frozen, remove the fruit and place it into storage bags or containers that are clearly labeled with the contents and the date.

XII Make up a plan of the text.

flat baking sheets; freezer bags; reusable containers; tight-fitting lids; permanent marker
