What shall I do with a quantity of Pippins just off the tree?

The apples are fresh, firm, and tart, though not as much so as they might be if we lived in a colder region. I’d like to bake something with them and not leave them all to the opossums and the yard waste collection. There are too many just to eat.

I can’t overdo the sugar, so no full-strength syrupy pies or tooth-aching cobblers for me. In fact, something a little diet-conscious would be best.

What would you do with a basket of fresh green Pippins?
