Equipment Needed

Instructions
Step 1: Blend the Watermelon
Place the cubed watermelon in a blender. Blend until completely smooth. You should end up with about 3 cups of watermelon juice.
Tip: If your blender struggles, add a splash of water to help it along.
Step 2: Strain for Smoothness
Pour the blended watermelon through a fine mesh strainer into a large bowl or pitcher. This removes pulp and seeds for a smoother texture.
Step 3: Combine with Lemon and Sweetener
Add the freshly squeezed lemon juice and sugar into the watermelon juice. Stir until the sugar is fully dissolved.
Step 4: Add Cold Water
Pour in the cold water and stir to combine. Taste and adjust sweetness as desired. Some prefer more tart lemonade; others like it sweeter—make it your own!
Step 5: Serve Over Ice
Fill glasses with ice cubes and pour in the watermelon lemonade. Garnish with mint leaves and lemon slices for a festive touch.
Health Benefits of Watermelon and Lemon
Watermelon is more than 90% water, making it incredibly hydrating. It’s also packed with nutrients like vitamin C, vitamin A, and lycopene—a powerful antioxidant linked to heart health and skin protection.
Lemons, on the other hand, are a rich source of vitamin C and help boost the immune system, aid digestion, and even support weight loss. When combined, these two ingredients create not just a flavorful drink but one that contributes to your overall well-being.
Seasonal Variations & Creative Twists
1. Sparkling Watermelon Lemonade
Swap cold water for sparkling water to add a fizzy twist. Garnish with a sprig of rosemary for an herbaceous note.
2. Frozen Watermelon Slush
Freeze the watermelon chunks before blending, then skip the ice and use a high-powered blender to make a slushy treat.
3. Watermelon Cucumber Lemonade
Add ½ cup of peeled cucumber for a spa-style upgrade. It brings a cool, clean flavor that pairs beautifully with lemon.
4. Tropical Watermelon Lemonade
Blend in some pineapple juice or coconut water for a tropical variation. Perfect for beach-themed parties!
5. Adult Twist
Add a splash of white rum, tequila, or vodka for a refreshing cocktail. Keep it light so the fruit flavors remain center stage.
