Yes. I love to flash freeze peaches and this method is ideal for use in smoothies. To flash freeze peaches: 1. Wash the peaches with cool water. Using a sharp knife, cut each peach in half around the pit. Gently twist each half to expose the pit. Using the knife, remove the pit from the peach. Slice the peach. 2. Place the sliced peaches on a parchment paper-lined baking sheet, making sure none of the peaches touch. Place the baking sheet in the freezer for 3 to 4 hours, or until firm. 3. Remove the tray and transfer the frozen peaches to an airtight bag. Make sure you squeeze as much air as you can from the freezer bag. Label the container with the date and freeze for up to 1 year.
