Peel and slice: Prepare the apples for the way you’d like to use them in future recipes. For smoothies, leave the skin on and dice them. For crumbles and crisps, peel and slice them.
Mix with lemon juice: To prevent browning, mix the apples with a bit of fresh lemon juice (just enough to lightly coat).
Flash freeze: Place the prepared apples on top of a baking sheet in a single layer. Flash freeze for 1 hour.
Place the apples in an airtight container or freezer-safe plastic bag. If using a bag, use a straw to suck any remaining air out of the bag and seal it.
Mark the “Use by” date. Use a permanent marker to label with a “use by” date that is 3 months in the future.
Freeze. Place the container or bag in the freezer and freeze for up to 3 to 6 months. For best results, use in 3 months. You can use frozen apples directly in cooked dishes; no need to thaw. They also work as a tasty snack right from the freezer!
