Here is the recipe I use to make delicious applesauce that also freezes very well. It will make app. 25 quarts so note when making it. I just made 50 quarts to freeze. My family loves it! I do use Back to Basics food strainer and sauce maker. Amazon has them for $49. Your local farm store may have them also. Trust me, it is worth the $. I use mine for all kinds of fruits and veggies.
First go to your local orchard and ask for 2 bushels of the seconds (it is cheeper this way) of the following:
Jonathon, Mac Intosh, Gala, Delicious & Courtland.
Bring large pots of water to a boil and put in your apples whole (do nothing to them). Boil until soft.
Then run them through the food strainer/sauce maker. It does all the work for you. You are left with the sauce. I then just keep making it until I fill a large stainless steel bowl full and add 3 C. sugar and sprinkle cinnamon all over the top. Then I put it in plastic quart containers and freeze. It is so easy! Hope this helps.
