- Ice cubes: Keeps your drink extra cold on a hot summer day.

How to Make the Most Refreshing Watermelon Lemonade
This easy lemonade recipe comes together in just three simple steps.
Step 1: Blend the Watermelon
Cut your good watermelon into chunks and remove any black seeds. Place the pieces into a food processor or Vitamix blender, then blend until completely smooth.
Step 2: Strain for the Smoothest Lemonade
For the best results, pour the watermelon puree through a fine mesh strainer or cheesecloth into a large mixing bowl. This removes excess pulp and creates a smoother drink.
Step 3: Mix Everything Together
- Pour the strained watermelon juice into a large pitcher.
- Add the fresh lemon juice, sugar, and cold water. Stir with a large spoon until the sugar is fully dissolved.
- Taste and adjust—want it sweeter? Add a little bit more sugar. Prefer more tartness? Squeeze in extra lemons.
Step 4: Serve & Enjoy
Fill glasses with ice cubes, pour in the delicious watermelon lemonade, and garnish with lemon slices and a sprig of mint.
