I don’t know about anyone else but after Memorial Day our family sure had a lot of watermelon left over! Now the question was what to do with it. Of course, there is always Watermelon Cucumber Mint Salad or a delicious Watermelon Pineapple Splash, but my mind immediately went to an alcoholic drink. Must be the heat talking!

I made a Watermelon Sangria last year for July 4th, which was super popular, but this time I wanted something a little on the sweet but tangy side. Umm, fresh juicy watermelon would go perfect with tequila and, being that margaritas are one of my favorite drinks, it just seemed like the thing to do.

And did it ever come out great! It was like drinking summer in a glass. It came out cool and refreshing with just enough tartness to make it a cocktail rather than a punch. My husband and I enjoyed them so much that I know I’ll be making them again real soon.
