Watermelon Basil Lemonade – Homemade lemonade sweetened with basil sugar and fresh watermelon juice.

There are a few things as synonymous with summer as lemonade. A glass of cold lemonade can make even the muggiest, humid day feel better. I love making my lemonade from scratch. Doing so allows me the freedom to try out new flavors – like this Peach Lemonade.
I love using watermelon in drinks – like this sangria and this margarita. Watermelon is also major symbol of summer so it’s only natural that I pair it with lemonade. And to make it even more complex in flavor, I added in some fresh basil.
Without further ado, here is my Watermelon Basil Lemonade!



Tips & Tricks
- Blend watermelon until smooth. To ensure the watermelon puree has very little pulp, you must blend it for at least a minute.
- Break the basil into the sugar. To get the most flavor from the basil, it is broken into the sugar with a wooden spoon.
- Don’t skip the salt. With a drink as sweet and sour as this lemonade, you need a little salt to balance it all out.
