Frozen apples can be used to make apple butter, applesauce, jam, jelly, pies, cakes, cobblers, baked apples, and other baked or cooked dishes.
Wash, peel, core, and slice the apples to your preferred size. It is best to keep the pieces rather large; the smaller cuts might get too mushy during the thawing process.
Dip prepared apples in a bowl of water with lemon juice stirred in (about a tablespoon per gallon) to prevent browning.
Place the apple pieces on a baking sheet in a single layer not touching, and freeze thoroughly. This step keeps the pieces from sticking together and you will be able to pull out the amounts you need later.
Once frozen, transfer apples to freezer bags, seal, and label the bag with the measurement and freezer date.
