Clean and simple, it just takes a blender to whip up this DIY watermelon juice. You can enjoy this refreshing drink with no added sugar on its own, or jazz it up with one of our variations (see below).
To make ahead: Cover and refrigerate juice for up to 4 days. Stir before serving.
Spicy Watermelon Juice: Cut 2 serrano peppers in half; muddle (seeds included) in a small pitcher until a chunky paste forms. Stir in watermelon juice; let stand for at least 30 minutes or up to 1 hour. Combine 2 Tbsp. kosher salt and 1 Tbsp. chili powder on a small plate. Run a lime wedge around rims of 4 glasses; dip the rims into the salt mixture, rolling them around to coat. Fill the glasses with ice. Pour the juice mixture through a fine-mesh strainer into the glasses. Discard solids. Garnish the glasses with lime wedges and sliced serrano.
Watermelon Lemonade: Combine 2 cups cold water, 1/2 cup sugar, and 1/2 cup fresh lemon juice in a large pitcher; stir until the sugar is dissolved. Add watermelon juice; stir to mix. Pour the mixture into 4 ice-filled glasses. Garnish with lemon wedges and fresh mint.
Watermelon Margarita: Combine 1 cup watermelon juice, 1/3 cup silver tequila and 1/4 cup fresh orange juice in a cocktail shaker. Add ice; cover and shake vigorously to mix. Place 2 Tbsp. kosher salt on a small plate. Run a lime wedge around rims of 2 glasses; dip the rims into the salt, rolling them around to coat. Fill the glasses with ice. Strain the juice mixture into the glasses. Garnish with lime wedges.
