Watermelon Margarita Float

These watermelon margarita floats are a bright and refreshing summer entertaining beverage. With the addition of watermelon sorbet, these margaritas are more than just a cocktail! 

Watermelon Margarita Float

During the summer, there’s nothing quite as refreshing as biting into a icy cold watermelon. Just thinking about watermelons already makes my mouth water.

What’s the deal with watermelons these days? I can’t seem to find watermelon WITH seeds anywhere. I miss the watermelons I ate as a kid studded with black seeds.

As a child, were you told that if you ate the seeds you’d grow a watermelon in your belly? Ever the skeptic, I ate dozens of seeds for verification. What did I learn? Adults lie to kids ALL THE TIME.

Nowadays it seems like seedless watermelons are all I can find. One day when I live in a house with a yard, I’ll grow some heirloom variety of seeded watermelons. And I won’t tell any future kids/nieces/nephews about the watermelon seeds growing in your belly story. I’ll scare them into helping me with the garden/cleaning instead.)

Here’s the third cocktail float in my summer series!  We started with cucumber gin and tonic floats and followed with (my fav!) grapefruit greyhound floats.  Today, the California girl in me rejoices because it’s time for watermelon margarita floats!

I’ve taken this fresh lime margarita and amped the flavors with watermelon juice and watermelon sorbet.

While I think the seeded watermelons are far superior, seedless watermelons do have their shining moments. Seedless watermelons are perfect for juicing, smoothies, and sorbets.

Not only this cocktail float delicious (Alex finished his in record time), it “feels” hydrating. For me, anything with watermelon during summertime is rejuvenating.

Whether you’ll be spending your weekends lounging by the pool or plopped on the couch watching Parks and Recreations marathons (like me), you’ll need this juicy, boozy, and pretty cocktail in hand.

For the kids and non-drinkers, you can float the watermelon sorbet in Sprite, 7-Up, or ginger ale. It tastes fantastic!

I loved the watermelons with the seeds in them! Do you remember the Rugrats episode where Tommy, Phil, and Lil went inside Chuckie because he swallowed a watermelon seed? That was the only time I ever heard that rumor!

I don’t know when I last had a float of any kind. All your float recipes are really making me crave one right now, but especially this watermelon one. I am long overdue for some watermelon in my life too.
