Similar to a margarita, this tequila-based cocktail gets an upgrade with fresh watermelon juice. Ultra-refreshing and hydrating, this summertime cocktail is the perfect combination of citrusy bubbles, seasonal summer produce, and a splash of booze.
Combine watermelon juice, tequila, and lime juice in a cocktail shaker or tall glass, stir to combine. Rim serving glass with salt, if desired; fill with ice. Pour watermelon mixture over ice; top with La Croix.
