To make syrup, add all ingredients in a small pot over low heat. Stir together until the sugar is dissolved and the mixture is lightly steaming. No need to boil. Remove from heat and let sit for five minutes. Then cool either by placing in the fridge or add the pot to an ice bath to cool rapidly. Blend mixture to finish syrup. Optionally strain out any solids.
To make a margarita, combine syrup (2-3 ounces per two margaritas depending on how spicy you can take it), with margarita mix, fresh lime, and tequila or mezcal. Shake well with ice. Strain into glasses with a salt rim. CHEERS!
