Print Recipe


  • 1 cup water
  • 1/2 - 1 cup low carb sweetener (see information in post about sweetener options and amounts.)
  • 1/16 teaspoon xanthan gum (optional; for thickening)
  • pinch salt (optional, for added flavor)
  • dash vanilla (optional, for added flavor)
  • dash stevia extract powder or a few drops of liquid stevia (optional; for added sweetness)


  • Blend sweetener in a blender / food processor until finely powdered.
  • In a small pot, combine the water and the low carb sweetener(s).
  • Stir to dissolve (it's dissolved when the mixture is completely clear.
  • Allow the mixture come to a simmer.
  • Once simmering, add the optional xanthan gum, salt, and vanilla, if using.
  • Cover and let simmer until the sweetener is dissolved.
  • Remove from the heat and cool completely before using.


You shouldn't have too much trouble with crystallization of this syrup, but if you'd like to take added precautions, here's what to do.
Add the sweetener and water to the pot slowly to prevent granules of sweetener ending up on the sides or edges of the pot.
Use a pastry brush to push any granules into the mixture while heating.
Use a clean utensil to stir the mixture.
Use a clean container to store the syrup with no traces of granulated sweetener.
Don’t stir the mixture once it's simmering as this can cause sweetener to drift onto the sides of the pan.
Add acid: adding a dash of an acid to the mixture can help prevent crystallizing.
Simmer with a lid on.  Condensation while simmering will help pull any crystals back into the mixture.
