Very easy and so much better than anything purchased in a store.
I cut 6 peeled and cored apples in half and placed them in a casserole dish with a few tablespoons of water and several dashes of cinnamon.
Microwaved for 12 minutes (2 minutes per apple). Let them cool a little and mushed them in a food mill (borrowed from my sister) with the coarse grater.
Ridiculously simple. Ridiculously delicious.
