Blueberry Apple Butter Recipe

Place apples in a slow cooker. Cook on High stirring occasionally until apples are softened and broken down about 3 hours. Add blueberries sugar cinnamon nutmeg allspice and cloves; stir to combine. Lower temperature to Low. Simmer until apple butter is thickened stirring often 8 hours.

Sterilize the jars and lids in boiling water for at least 5 minutes. Pack apple butter into the hot sterilized jars filling the jars to within 1/4 inch of the top. Run a knife or a thin spatula around the insides of the jars after they have been filled to remove any air bubbles. Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with lids and screw on rings.

Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars into the boiling water using a holder. Leave a 2-inch space between the jars. Pour in more boiling water if necessary to bring the water level to at least 1 inch above the tops of the jars. Bring the water to a rolling boil cover the pot and process for 15 minutes.

Remove the jars from the stockpot and place onto a cloth-covered or wood surface several inches apart until cool. Once cool press the top of each lid with a finger ensuring that the seal is tight (lid does not move up or down at all). Store in a cool dark area.
