Notes
To Make Simple Syrup combine equal amounts water and sugar and heat on medium just until the sugar melts. Remove from heat, pour into a vessel and put in the refrigerator to chill before using.This cocktail only requires a small amount of simple syrup but any leftovers can be stored in the refrigerator in a closed container and should last for at least 2 weeks.Serving a holiday crowd and want to both extend the quantity and lessen the alcohol content a bit? Pour the mixture over ice and leave enough room to top it off with some chilled sparkling soda. Gently stir, garnish, and serve.
