I canned 13 pints of applesauce, using the apples from our tree naturally. Our tree is a Harelson and the apples are abundant this year. I've frozen 2 gallons of ziplock bags and 1 gallon of dried apples.
I found this site to be especially helpful for canning applesauce.
The recipe I used:
3 pounds of apples, peeled, cored and sliced
3/4 c water
2-4 T sugar
2 T lemon juice
1 cinnamon stick
Cook over low heat until it's mushy.
