Refreshing Watermelon Lemonade Ingredients

- 6 cups (1.4 L) water, divided
- 1 cup (200 g) granulated sugar (can substitute with honey or agave syrup for a healthier option)
- 5 cups (854 g) cubed seedless watermelon (chilled for best results)
- 1 cup (236 ml) fresh-squeezed lemon juice (about 4-6 lemons, depending on size)
- Additional sliced watermelon and lemon for garnish (optional, adds a decorative touch)
Step-by-Step Watermelon Lemonade Instructions
- Make the simple syrup: In a small saucepan, combine 1 cup (236 ml) of water with the granulated sugar. Cook over medium-low heat, stirring frequently, until the sugar is completely dissolved. Remove from heat and set aside to cool.
- Blend the watermelon: Place the cubed watermelon in a blender and puree until completely smooth.
- Strain the watermelon juice: Pour the pureed watermelon through a fine mesh strainer into a large pitcher. Use a spatula to help nudge the juices through. Discard the pulp.
- Combine the ingredients: Add the prepared simple syrup, fresh-squeezed lemon juice, and the remaining 5 cups (1.18 L) of water to the pitcher. Stir well to combine.
- Chill or serve immediately: Chill the lemonade in the refrigerator until cold (stir before serving) or pour over ice to serve immediately. Garnish with additional watermelon slices, lemon slices, or mint sprigs if desired. Note: The watermelon will settle as the lemonade sits, so always stir well before pouring.
Perfect Pairings: Serving Suggestions
This refreshing Watermelon Lemonade pairs beautifully with light summer dishes like grilled chicken salads, fish tacos, or veggie skewers. For a fun twist, serve it in hollowed-out watermelon halves as a festive drink dispenser. Don’t forget to garnish with extra watermelon slices, lemon wheels, or mint sprigs for a pop of color and flavor!
Make It Your Own: Recipe Variations
Customize your Watermelon Lemonade by adding a splash of sparkling water for a fizzy version or a hint of fresh basil for an herbal twist. For a tropical vibe, blend in a handful of pineapple chunks or a splash of coconut water. If you’re feeling adventurous, a splash of vodka or tequila can turn this into a delightful cocktail for adults.
Keep It Fresh: Storage Tips
Store your Watermelon Lemonade in a sealed pitcher in the refrigerator for up to 2 days. Since the watermelon pulp may settle, give it a good stir before serving. For longer storage, freeze the lemonade in ice cube trays and use the cubes to chill future batches without diluting the flavor.
Quick Tips for Success
To save time, use pre-cubed seedless watermelon from the grocery store. If you don’t have a fine mesh strainer, a cheesecloth works just as well for straining the puree. For a smoother texture, blend the watermelon in batches to ensure it’s completely pureed before straining.
