To make the hot honey, combine all ingredients into a microwave-safe bowl. Heat for 1 minute on high. Stir, and heat an additional 20-30 seconds until the granules are dissolved. Let cool slightly. Leftover hot honey will keep for up to 2 weeks in the fridge.
In a shaker, combine the tequila, grapefruit juice, hot honey, and lime juice. Add ice and shake until cold. Pour into your favorite cocktail glass and top with grapefruit soda or sparkling water. Garnish with mint and a couple wedges of grapefruit, as desired.
