Nothing feels more like summer than fresh watermelon juice dripping down your chin. Instead of going to town on fat wedges—which, admittedly, is the world’s best snack—why not blend it into a cocktail and drink it straight from the melon? This tart and floral watermelon rum punch is a delightful brunch sipper all afternoon long. The star of the show may be the melon, but this drink’s flavor power owes a lot to St-Germain, a sweet elderflower liqueur. And not for nothing, using an actual small watermelon as a cup (complete with a few cocktail umbrellas and silly straws) is pretty damn Instagrammable.  Cut the top off a small watermelon and scoop the flesh into a blender. After blending and straining the fruit, pour the juice back into the hollowed-out melon. Add rum, St-Germain, lime juice, and a bit of simple syrup (though you could just up the St-Germain a bit for the extra sweetness). Give the cocktail a stir, then add plenty of ice. Keep in mind that while the melon may be on the small side, this recipe still makes four servings of cocktail, so grab a few friends when you’re ready to start sipping.Watermelon Rum PunchKitchen gear kindly provided by our partners at
