15-Minute Watermelon Hibiscus Mocktail

A vibrant, refreshing mocktail that combines the natural sweetness of watermelon with the tart floral notes of hibiscus tea. Fresh ginger adds a subtle spice while lime and lemon juices provide bright acidity. The deep red hibiscus creates a beautiful color contrast with the pale watermelon juice. Perfect for summer entertaining, picnics, or as a sophisticated alcohol-free option at parties. Can easily be spiked with rum for those who prefer an alcoholic version.
