What can I do with apple peel? I made an apple pie the other day and peeled 6 or so apples.  I ended up composting the peelings, and it got me wondering, what else could I have done with them?
You could use them, together with the core, to make apple-glaze (for your pie).  Cover everything with water, simmer about 30 min, strain, simmer until you reach the desired density.
