Watermelon Cosmo

This Watermelon Cosmo is a fresh summer twist on the classic cosmopolitan! Use fresh watermelon juice in the drink and a slice for the garnish!

My wife and her family are always drinking cosmsos, my father in-law has become an expert at making them in assembly line fashion. Every holiday at their house it seems like that’s all he’s doing is making more comopolitan cocktails.

Since it’s watermelon week, I added fresh watermelon juice to a cosmopolitan in place of the cranberry juice – and it was a success! Not as tart as the cranberry juice so I held back a little on the triple sec which is also sweet and added a little more fresh lime juice instead.

You could totally make these up ahead of time, too. Like in large amounts so you don’t have to play bartender all night! Then when you’re ready just add a serving to your shaker with ice and shake them up individually.

I used Three Olives Watermelon Vodka for these Watermelon Cosmos, of course, but you can use plain vodka if you don’t have any, it’ll just be a bit stronger tasting. Not that that’s a bad thing at all…

If you’re only making one or two, all you have to do is take about a half a cup of fresh watermelon cubes and place it in the bottom of your cocktail shaker. Muddle the watermelon until it’s almost all liquified and then add your ice and the booze. Shake it up well then strain into a martini glass.

If you’re making a pitcher of these for a crowd you can add the watermelon into a large pitcher, muddle it, add the booze and then just stash it in the fridge. Then when you’re ready, pour about a cup into your martini shaker and serve individually.

For our family though, there no point in making one or two – the pitcher will be coming out for sure!
