Ingredients
To make this vibrant and refreshing watermelon lemonade, you’ll need just a few fresh and simple ingredients:
- 4 cups seedless watermelon (cubed) – chilled and sweet for the best flavor
- ¾ cup fresh lemon juice (about 4–5 lemons) – adds a bright, tart contrast
- ½ cup cold water – helps dilute and balance the flavor
- ¼ to ⅓ cup simple syrup (adjust to taste) – made by dissolving equal parts sugar and water
- Ice cubes – for serving
- Optional: Fresh mint leaves or lemon slices – for garnish
Ingredient Notes:
- Watermelon: Choose a ripe, sweet watermelon for natural flavor. Look for a deep yellow spot on the rind and a hollow sound when tapped.
- Lemon juice: Always use freshly squeezed lemon juice—bottled juice won’t give the same brightness.
- Simple syrup: Adjust the amount based on how sweet or tart your watermelon is. You can also use honey or agave syrup as alternatives.
Instructions
Making this watermelon lemonade is as easy as blend, strain, and chill. Here’s how to do it:
Step 1: Make the Simple Syrup
In a small saucepan, combine ½ cup of sugar and ½ cup of water. Heat over medium heat, stirring until the sugar is fully dissolved. Remove from heat and let cool completely.
Step 2: Blend the Watermelon
Add 4 cups of cubed seedless watermelon to a blender. Blend until smooth. This will create a vibrant pink juice with a pulpy texture.
Step 3: Strain the Juice
Place a fine mesh strainer over a large bowl or pitcher. Pour the blended watermelon through the strainer to remove pulp, pressing gently with a spoon to extract as much juice as possible.
Step 4: Add Lemon and Sweetener
Stir in ¾ cup of freshly squeezed lemon juice and ¼ to ⅓ cup of the cooled simple syrup. Taste and adjust sweetness as needed.
Step 5: Add Water and Chill
Pour in ½ cup of cold water to thin the lemonade slightly. Stir well. Refrigerate for at least 1 hour to chill and allow the flavors to meld.
Step 6: Serve Over Ice
Fill glasses with ice cubes. Pour the chilled watermelon lemonade over the ice. Garnish with fresh mint leaves or lemon slices if desired.
Pro Tips and Variations
This watermelon lemonade is incredibly simple to make, but these tips and variations will elevate it even further:
Pro Tips:
Use ripe, seedless watermelon: Choose a sweet, vibrant red watermelon for the best flavor. A ripe melon will give your lemonade a deeper color and more natural sweetness.
Chill all ingredients beforehand: For the coldest, most refreshing drink, refrigerate your watermelon, lemons, and even the simple syrup before mixing.
Strain thoroughly: For a smoother texture, strain the blended watermelon using a fine mesh sieve. This removes excess pulp and seeds.
Adjust sweetness to taste: Depending on how sweet your watermelon is, you may need less or more simple syrup. Always taste before serving.
Serve immediately after chilling: Watermelon juice can separate if left too long. Stir well before serving and enjoy fresh for the best experience.
Delicious Variations:
Watermelon Mint Lemonade: Add a handful of fresh mint leaves while blending or as garnish for a cool, herbaceous twist.
Ginger Watermelon Lemonade: Blend ½ to 1 teaspoon of grated fresh ginger with the watermelon for a spicy-sweet flavor.
Sparkling Watermelon Lemonade: Replace the cold water with chilled sparkling water or club soda for a fizzy upgrade.
Frozen Watermelon Lemonade: Freeze watermelon cubes ahead of time and blend with lemon juice and simple syrup for a slushy-style treat.
Cocktail Version: Add a splash of vodka, gin, or white rum to make an easy summer cocktail for adults.
