Crock Pot Apple Butter

6 apples

2 tsp. cinnamon

1/4 tsp. nutmeg

1/4 tsp. cloves

1/2 tsp. allspice

1/4 tsp. salt

3/4 c. light brown sugar

1 c. apple cider

1 lemon peel

Peel apples and chop into pieces about 1/4 to 1/2 inch thick; add to crockpot. Add spices, salt, sugar, cider and lemon peel. Stir to combine. Cook on high for 1 to 1-1/2 hours, or until apples are bubbly. Reduce heat to low and cook for 6 to 8 hours, stirring 2 or 3 times throughout. Turn off heat and allow to cool about 1 hour. Remove lemon peel and pour mixture into food processor or blender; puree until smooth.
