A refreshing sparkling summer drink of watermelon and lime.

Watermelon Lime Soda

Summer temperatures are here and with them, my aversion to turning on the oven. I still do plenty of baking in the summer, just not as much, and usually only in the morning. So when I had a hankering for something sweet and refreshing on one particularly hot afternoon earlier this week, I turned to one of my new favorite things— club soda flavored with the perfect summer flavor combo, watermelon and lime.

This beverage is super easy, very refreshing, and a million times better than whatever processed fountain drink you’re currently a slave to. So ditch the drive-thru and make a pitcher of this flavored soda instead, I guarantee you won’t regret it.

I love a good cocktail as much as the next gal, but often this alcohol-free drink is all I need. Still, I have been known to add a splash (or two) of vodka, gin, and even rum to to my glass to kick it up a notch. Perfect for summer weekend sipping.

The most important thing to remember is that flavored sodas are 100%  customizable. Buy a bottle of club soda or sparkling water and go crazy! Strawberry and basil, raspberry lemonade, peaches and mint… the options are endless.
