Freezer-Safe Containers

The container must be freezer proof so that it will not crack or break when the content freezes. It must also have an airtight seal to prevent moisture loss and leakage, and to keep food from absorbing unwanted odors. Rigid freezer containers are probably best used for freezing foods that have a fair amount of liquid added, such as water, juice or syrup. Freezer-safe plastic containers with tight fitting lids or waxed cardboard cartons, such as milk cartons, work well. Be sure the waxed cartons are sealed tightly. Square or rectangular shaped rigid containers are better than round for using freezer space efficiently. Using the same size and shape containers will also help use freezer space more efficiently. Be sure to leave the proper amount of headspace to allow for the contents to expand when it freezes but do not leave to much empty space in the container because it will expose the content to too much air.

Sealable freezer bags are another option that works well for whole, sliced or slightly crushed foods where there is minimal liquid involved. The flexibility of the bag makes it more difficult to fill without spilling when the food has a lot of liquid. Be sure the plastic bags are sealed completely and that all the air has been pressed out. Place freezer bags flat on a solid surface to freeze, such as a baking sheet. Do not place in freezer baskets while they are first freezing because they will form around the wire and be hard to get out or the bag may get punctured as it expands while freezing. Once the packages have completely frozen, they can be taken off the baking sheet and stacked neatly in one of the baskets.
