The Lavender Mule is a snazzy little Moscow Mule variation. It involves making lavender syrup (worth it), the recipe for which is below: 0.5 cup sugar 1 cup water 2 tablespoons dried culinary lavender. Combine the sugar and dried food-grade lavender in a heat-proof bowl. Pour boiling water over the sugar and lavender, and stir for a few seconds until the sugar is dissolved. Let the lavender steep for 10-15 minutes. Strain the lavender out and let the syrup come to room temperature, then refrigerate.
