Micheline, I thought about freezing them separately on a cookie sheet like I do berries. However, from what I could find, it sounded like it was important to keep them surrounded by the juices during freezing. The recipe sounds wonderful; I don't blame you for lusting.
White Swan, someone else just told me pretty much what you mentioned. Sprinkle lightly with sugar and lemon juice to extract the juices a little before freezing. That's probably what I'll do. I hate to mess this up since these peaches are absolutely perfect. I sure wish we still had our peach tree. Thanks much!
