The best place to get it are the Amish Shoppes here (USA)-I think it might be best to try and make it though. I will look for a recipe for you.
This website is good:

Just ask me if you do not understand the measurements or directions. Sour apples make the best applebutter. It is a diet food for them because it is low fat and traditionally made with many spices so you just use a small amount in place of butter and jam.
Wait though-it is high carb-that was he point of the post.
