We also have a big surplus of apples (regular ones.) Some of the things that we make from them are:
Apple Cider Vinegar: So easy to make. Can be made from the flesh, or for a light, elegant vinegar, use the skins only.
Hard, Fizzy Cider: My DH makes beer and hard, apple cider every year. It's way better and far cheaper than what you can buy in the store and both are super refreshing on a hot, summer day.
Apple Cider Soda Pop: This is natural soda with probiotics. Easy...takes just a few days, especially during this warm weather.
Plain, Old Apple cider: Just juice them and enjoy. You can freeze the juice too.
I'll be glad to send over some recipes, or steer you toward some websites, if you're interested in any of these. Let me know.
