Ingredients

Scale

Fruit and Sweeteners

  • 3 pounds fresh blueberries
  • 1 ½ cups light brown sugar
  • 1 tbsp honey

Flavorings

  • 1 lemon, zested and juiced
  • 1 tsp cinnamon
  • ¼ tsp nutmeg

Instructions

  1. Combine Ingredients: Add the fresh blueberries, light brown sugar, honey, lemon zest, lemon juice, cinnamon, and nutmeg to your slow cooker. Stir well until all the ingredients are evenly mixed together.
  2. Cook on High: Cover the slow cooker with its lid and cook the mixture on the high setting for 1 hour. This initial cooking softens the berries and helps dissolve the sugar.
  3. Blend the Mixture: After cooking, carefully transfer the blueberry mixture into a blender. Blend until it reaches a smooth, buttery consistency without any large chunks remaining.
  4. Return to Slow Cooker: Pour the blended blueberry mixture back into the slow cooker. Prop the lid slightly ajar with a wooden spoon to allow steam and excess liquid to escape during the next cooking phase.
  5. Slow Cook on Low: Cook the blueberry butter on low heat for an additional 4 to 5 hours. This slow evaporation thickens the butter and intensifies the flavors.
  6. Store: Once thickened to your liking, ladle the blueberry butter into clean jars. Store the jars in the refrigerator, where it will keep fresh for up to 2 months.

Notes

  • Use fresh, ripe blueberries for the best natural sweetness and flavor.
  • Adjust the sugar amount depending on your preferred sweetness level or the tartness of your blueberries.
  • Prop the lid with a spoon during the second cooking phase to allow the mixture to thicken without boiling over.
  • Use clean, sterilized jars for storing blueberry butter to extend its shelf life safely.
  • This recipe is naturally gluten-free, vegetarian, and low in fat.
