Watermelon and Pink Grapefruit Frozen Margaritas - a fun, festive and refreshing summertime beverage!

For those of you who are celebrating the July 4th holiday here in the US – we hope you have a wonderful day today!  And what better way to celebrate than with a fun, frosty cocktail like our Watermelon and Pink Grapefruit Frozen Margaritas!

Yesterday, we shared a post about our recent trip to Atlantic City – and as part of that trip, Jack and I decided to sign-up for a class at the Viking Cooking School located inside the hotel where we stayed.  (We’ll share some photos from our cooking class next week!)

Watermelon and Pink Grapefruit Frozen Margaritas - a fun, festive and refreshing summertime beverage!

Our recipe today was inspired by a watermelon margarita that was served during that cooking class – but we changed the recipe up (like we usually do!) to include some pink grapefruit as part of the frozen fruity mix!  The grapefruit is a delicious complement to the sweet watermelon and combined with lime juice, tequila and triple sec – this is unlike any frozen margarita you’ve ever had before!

You can make your watermelon and pink grapefruit frozen margaritas a little more festive by putting colored sugar on the rim (we tell you how to do it in the recipe) plus a slice of lime, and a thin wedge of watermelon for garnish.  And – if you prefer salt on the rim of your margarita glass, you can also use the same technique to color coarse kosher salt.

  • 3 cups seedless watermelon, cubed and frozen
