Here is the recipe for my own apple spaghetti sauce:
4 lbs. apples (peeled, sectioned and cored)
2 packages "Italian style spaghetti sauce mix" (found at Wal-mart in the dry sauces aisle)
and yes, there is no tomato in this mix.
2 onions (chopped)
1 3/4 cup water
Directions: Place all ingredients in a crock pot. Leave lid off for an hour on high. Then place the lid on and cook on high for 4 hours. Then pour all of the mixture in to a blender or food processor until smooth. Taste it and if its too sweet, you can add more onion powder, oregano, some salt, and some powdered Parmesan cheese to the mix. It is now ready to can or freeze!
This turns out sweeter than a tomato recipe, but for someone who can't eat tomato, it's yummy.
