To freeze apples, choose the right type of apple for freezing, decide between cutting them up or freezing whole, and freeze them in an appropriate container. To prevent browning of the cut apples, soak them in a solution of ascorbic acid.
Some good apples to choose for freezing include Granny Smith, Rome beauty, golden delicious and Jonathan apples. Don’t use apples with meaty textures. Make sure the apples are ripe, firm and crisp. Do not freeze apples that are not yet matured or have bruises. When freezing cut-up apples, wash them in cold water first. Peel the apples, core them, and cut them into slices.
To avoid having clumped apple slices, dry pack them first. This involves placing the slices in a single layer on a cookie sheet. Put it in the freezer just until they become solidly frozen. Remove them from the cookie sheet, and place them into freezer bags or containers.
It is also possible to freeze apples whole with the skins on. For this method, wash the apples, and drain them. Core the apples, and let them dry on a towel. Put the cored apples in freezer bags, and place them in the freezer. When it is time to use the apples, run them under cold water before peeling.
