  2. Take off lid and cook for another 30 minutes on low.

  3. Hand blender to puree the blueberries right in the slow cooker. Or transfer blueberries to regular blender and blend then pour back in the slow cooker.

  5. Now stir brown sugar, nutmeg, allspice, cinnamon and lemon juice until combined.

  6. Replace lid, again leaving a small crack in lid to allow air to escape. Over the next hour, the blueberry butter should thicken to your desired consistency.
