Recipe for Watermelon Lemonade

Since May temperatures in Sacramento, where I live, frequently reach the triple digits, we’re making this simple lemonade early and often this summer. I always keep one or two watermelons on hand for quick snacks because my boys are watermelon addicts. Making a refreshing drink out of watermelon is a great way to stay cool throughout the summer.
Ingredients for Watermelon Lemonade
Making homemade lemonade doesn’t require many ingredients. You’ll notice that this is the best-tasting lemonade ever thanks to a few simple additions. Let’s examine what you will require:
- Seedless watermelon: Cut into cubes that are 1-2 inches in size. It’s acceptable if you can’t find watermelon without seeds; just make sure to remove the seeds before beginning.
- Granulated sugar: To make the lemonade sweeter.
- Lemon juice: Juice from roughly four large lemons.
- Lime juice: Complements watermelon and balances the flavor. One large lime will suffice.
- Honey or agave nectar (optional): If you would like it a bit sweeter.
- Garnishes (optional): Slices of watermelon, lemon, lime, and/or fresh mint leaves.
How to Prepare Lemonade with Watermelon
It takes about five minutes to make this simple lemonade recipe! To break down the sugar in this lemonade, we will blend it with the watermelon rather than making a simple syrup.
- In a blender, combine the water, granulated sugar, and cubed watermelon. Blend until extremely smooth.
- Using a strainer, transfer the watermelon juice into a large bowl or pitcher.
- Add the agave (if using), lemon juice, and lime juice to the pitcher and stir.
- Transfer to glass cups and garnish with fresh mint and a watermelon slice.
FAQs for Watermelon Lemonade
- Storage: This lemonade can be kept in the fridge in a covered pitcher. It will have separated, so use a long spoon to stir it up before drinking.

- Freezing: Although freezing this lemonade is a fantastic idea, we would much rather turn it into popsicles!
