I made applesauce with all the ida reds that we picked last month. It's very easy, but be prepared to do a lot of chopping! I brought the cutting board in front of the TV and dropped all the slices into a crock pot every time they started to pile up.
Adapted from The Joy of Cooking
6 to 10 cups apple slices
an inch of water in the pan
the juice of one lemon
1 cinnamon stick
1/2 C brown sugar (optional)
Peel, core and slice apples into slices, taking a break to squeeze lemon juice over them once you get a good pile of them. I cut them in half first, then quarters, peeled the quarters and cut each in half or in thirds.
Fill the pan with about an inch of water and cook uncovered over medium heat, stirring once in a while, for about 20 to 30 minutes or until the apples have fallen apart. Stir in the brown sugar if using. You can puree the applesauce at this point to make it extra smooth, but I just stirred it and it was the right consistency.
