Notes

Variations and Pro Tips

Change the sweetener - I don't suggest brown sugar because of the molasses flavor, but try stevia, monk fruit, or another that you love to give this drink your desired sweetness.

Make it grown up - a watermelon vodka cocktail is a great spin on this recipe. You'll be sipping all summer long!

Try flavored sparkling water - bust out the LaCroix of your choice to give your soda another boost of flavor.

Make a watermelon soda float with a scoop of vanilla ice cream or a rainbow sorbet!

Add a flavored syrup - I make flavored simple syrups all the time for things and you can find them in posts like my strawberry lemonade, peach sweet tea, and so many cocktails.

Make Ahead Instructions

If you're making this ahead of time: Do not add the carbonated water. Use a lidded pitcher to keep the watermelon juice fresh for up to 2 days before serving. Add the seltzer water to serve.
