Two words: Watermelon. Lemonade.

We are a lemonade loving family. If it’s summertime, there’s always some form of lemonade in our fridge. Over the years I’ve made a few variations like this vanilla gem or the always favorite honey lavender. Last month I shared my “old fashioned” recipe and while making it, I thought about making a watermelon version. Simplified.

A refreshing lemonade that can be easily whipped up after a day out on the lake. One that didn’t require making a simple syrup or much effort at all. Who doesn’t like the idea of just throwing everything into a blender and (theoretically) pouring it over ice?

Pour the watermelon lemonade into a large pitcher and serve immediately.

Note: before serving, I recommend tasting and adjust the lemonade to your preference. Like it more lemony? Add more  (1/4 to 1/2 cup more) lemon juice. Love a super sweet lemonade? Up the powdered sugar. Easy-peasy.

pour watermelon lemonade over ice

To serve, simply fill a glass to the top with ice and pour that refreshing liquid gold over top. For a pop of color try adding a sprig of fresh mint to each glass. Deliciously fresh and thirst quenching. Tastes like the best of summer.
