Hi Do
Apples, apples, apples! Who doesn't love apples... or apple pie. :) Apples are versatile and make a great project for beginning canners. They are a higher acid fruit and that makes for some great water bath canning opportunities. Check out canning apples, applesauce, pie filling, dehydrating, freezing, and a video review of the Apple Peeler Corer Slicer. (how's that for a long name for a handy little tool)
