To freeze peaches, follow these steps for best results:

1. Rinse the fresh peaches and pat them dry.
2. Optional: If peeling is preferred, blanch peaches by boiling them for 1 minute, then plunge into ice water to cool, and peel off the skins.
3. Cut the peaches in half, remove the pit, and slice them to desired thickness.
4. Toss the peach slices with about 1 tablespoon of lemon juice per pound of peaches to prevent browning.
5. Arrange the slices in a single layer on a parchment-lined baking sheet and freeze until solid, about 4 hours.
6. Transfer the frozen slices to zip-top freezer bags or airtight containers, remove as much air as possible, label with the date, and store in the freezer.
7. Frozen peaches can last up to 6-12 months in the freezer.

This method helps retain flavor, prevents clumping, and makes it easier to use portions as needed for recipes like smoothies or baking.
