Before you freeze your canned creations, make sure you have the right equipment.
An accurate freezer thermometer will help you regulate your freezer temperature at 0 degrees F or below. Higher temperatures will cause food to deteriorate faster. When freezing vegetables and fruits you will need a colander plus a large pot, kettle, or saucepan with a wire basket.
A variety of freezer containers and materials are available. Whatever you choose should be moistureproof and vaporproof, able to withstand temperatures of 0 degrees below F, and capable of being tightly sealed. For liquid or semiliquid foods, use rigid plastic freezer containers, freezer bags, or wide-top jars specifically designed for freezing. Regular jars are seldom tempered to withstand freezer temperatures. For solid or dry-pack foods, use freezer bags, heavy foil, plastic wrap for the freezer, or laminated freezer wrap.
