Place the distilled water into a saucepan, along with the erythritol.

Take a 1/4 teaspoon measurer and fill it up on a 1/4 of the way with xanthan gum (this is a dry powder). Pour this into the saucepan and whisk well. NOTE: This is 1/16 of a teaspoon.

The xanthan gum will want to clump up, but do your best to whisk it into the erythritol and water mixture. Heat the mixture over medium to high heat and continue to whisk now and then. (Note: Eventually when the simple syrup is made and cooled you can shake up the bottle and any little clumps of xanthan gum will be shaken into the mixture.)

As it comes up to a boil, drop in 5 drops of sweet drops. In the final mixture, this will slightly increase the sweetness of the keto simple syrup without tasting like Truvia or Stevia, which many people do not think tastes as close to sugar as erythritol does.

As it reaches boiling, the xanthan gum will cause the mixture to thicken to the consistency of simple syrup. Let it boil for 45 seconds and then pull off the heat and cool. You can taste it and add more sweet drops if you desire a super-sweet simple syrup.

When cool, place in a mason jar and shake well to remove any specks of xanthan gum.

This sugar-free erythritol simple syrup lasts indefinitely and will not crystalize. It can be added to all sorts of keto cocktails.
