  • 3 cups blueberries
  • 3 tbs Lakanto monk fruit sweetener
  • 2 Tbs lemon juice
  • 1/4 cup water
  • 1/2 teaspoon Guar Gum or Xanthan Gum for thickness optional ingredient


  • Pour the blueberries, sweetener, lemon juice and water in a medium-sized saucepan.
  • Heat at a low temperature at cook it until the fruit has reduced into a sauce.
  • You can choose to leave the blueberries whole and make this a compote.  Or you can smash the blueberries to make the sauce thicker.  I prefer to smush them myself.
  • Once the sauce has fully cooked (I think it was 20 minutes at low temp for mine) I lightly sprinkle a 1/2 teaspoon of Guar Gum or Xanthan Gum to make the sauce a bit thicker.  This is an optional step.
  • I store the sauce in the refrigerator for up to 7 days in a closed mason jar lid.  I allow the sauce to cool completely before I put it in the refrigerator.
  • You can reheat the sauce when you are ready to use it again too.
