Pour water and sweetener into a small saucepan over medium heat on stove.
Bring to a boil and continue to simmer and stir for 3-5 minutes until sweetener is dissolved.
If you want to thicken, sprinkle in xanthan gum and whisk until dissolves and thickens, just needs 1-2 minutes.
Remove from heat and whisk in any flavorings you like. If using fresh mint leaves, add them to the water while its simmering then remove.
Cool then pour into mason jars for storing.
Storage: Covered on counter for 1 month or in the fridge for 6 months.
