A simple tutorial on how to freeze apples (or other fruit!) for cooking and baking.
Lay them out onto a baking sheet lined with parchment paper or plastic wrap, keeping them separated from each other as much as possible so that they don't stick together.
Freeze until solid, about 2 hours.
Pour into labeled ziploc bags, and return to the freezer until use.
Use as directed in your recipe. For some recipes, it may be necessary to thaw the apples before baking so that the juices can mix with dry ingredients to moisten them.
