2 ounces watermelon Juice (Trader Joe’s carries this)
2 ounces vodka
1 tablespoon fresh lime juice
1 teaspoon agave nectar (optional)
Mint leaves for garnish
Pour all ingredients in a shaker with a small handful of ice and shake for 30 seconds.
Serve over ice. Garnish with mint leaves.
I omitted the vodka and replaced it with Topo Chico mineral water. You could also substitute Sprite.
If you want to make your own watermelon juice, add cubed watermelon to a blender then strain through a fine mesh strainer.
