I just bought 54 pounds of peaches. I'm going to can some tomorrow. Tonight 36 pounds of them are in the freezer. I've heard that if you freeze them first, then blanch them VERY quickly, the peels just slip right off. I'm hopeful but we'll see.
I am considering using an apple corer to get the pits out, since 18 pounds of them are "cling" peaches. Seems like it would be easier than trying to remove the pit any other way. The corer I have also make 8 even slices, so I could slice them at the same time.
Anyways - I'll report back after I try it.
