1 (3 lb.) bag Rome apples, peeled and coarsely chopped (about 8 cups)
2 c. sugar
2 tsp. ground cinnamon (or to taste)
1 tbsp. apple cider vinegar

Put the chopped apples in a crock pot. Sprinkle the sugar and cinnamon over the top. Cover and cook on high for 1 hour, stirring occasionally. Add vinegar and stir. Reduce heat to low and continue cooking several hours until apples are the consistency of applesauce. Any large pieces of apples can be mashed with a potato masher or fork. Continue cooking to thicken slightly. Spoon into jars and seal immediately. Also freezes well.
