OVEN APPLE BUTTER

3-1/2 gal applesauce
8-10 lb sugar or to your taste
1 t oil of cinnamon
red food coloring, if desired

Place sauce in roaster pan with a lid. Put in oven at 300 degrees. Bake 3 hours; stir 2 times. As pulp has thickened, now add Sugar. Mix well. Place back in oven for about 3 hours more. (Stir from edges 4--6 times after sugar is added. Test when done to see if it is thick as you like by putting a spoonful on a plate. It is done when water does not form around the edge. Add flavor to your taste. Put in jars while hot. Seal.
Note- This can also be made in an open crock pot.
