A few days ago I happened to see this post from hipgirls, and I pinned it so that once I found a good price on organic apples, I could use my applesauce scraps to try making vinegar. Lo and Behold, $1.49/lb later, I was toting home some Galas and Braeburns and Golden Delicious.
So, I peeled and cored them and threw them in the crock pot for applesauce, and then the real fun began. Personally, I would only use organic apples for this, since the peels are involved.
I saved all the scraps (I used 10 apples) in my Pfaltzgraff batter bowl. Don't use a reactive container.
I needed 2 quarts of water mixed with 1/2 c sugar to completely cover the apples.
Cover with cheese cloth to keep out the fruit flies. (Borrow bungee cord from hubby's tool box. He won't mind.)
Let it sit at room temperature for a week. Strain, then continue to ferment for 2 or 3 more weeks (covered, of course) stirring occasionally. I'll post another update to let you know how it turned out, and how much the family complained because it stunk up the house...
