  • Using an immersion blender, blend the blueberry butter in the crockpot until it's completely smooth.

Notes

  • If you don't have a food processor, you could also use a large high powered blender to puree the berries.
  • The nutmeg is optional but it does add a nice warming background to it.
  • If the sauce is too thin for your preference after the 5 hours, remove the lid completely and continue cooking another 30-60 minutes to thicken it to your desired texture.
