I recently fell in love with watermelon juice and knew that I had to come up with a cocktail using it. These watermelon gin fizz slush drinks (or water-fizzes, as I now call them) are delicious and refreshing. The fresh mint (one of my favorite herbs) balances the sweet watermelon and gin to create the perfect summer cocktail.
Test Kitchen Notes
The only thing better than a piece of cold watermelon on a hot summer day is an icy watermelon cocktail all gussied up with fresh mint, lime, gin, and a splash of effervescence. The Frozen Watermelon Mint Gin fizz is the perfect make-ahead mixer, ready in your freezer until guests arrive. You can booze it up or keep it light. Either way, it’s sure to delight and refresh in every sip. —SwoonMySpoon
Fresh Mint & Lime Simple Syrup
Zest of two limes
fresh lime juice (of approximately 4 limes)
fresh mint leaves finely chopped
watermelon juice (from approximately half a watermelon)
To make the simple syrup: Combine all ingredients in a small sauce pan. Bring to a boil, making sure to stir until the sugar has dissolved. Once it has boiled and combined, remove from heat and allow to cool to room temperature. Then, either strain the mint leaves or use your stick blender to puree them into the syrup.
Juice approximately half a watermelon. This can be done with a juicer or by cutting into chunks and using a food processor or blender. I used my stick/immersion blender. After it is puréed, run through a mesh strainer/sieve to remove any pulp or seeds. A little pulp is fine, but try to get it as close to juice as possible.
Combine simple syrup and watermelon juice with 1 cup of gin (or vodka, if you prefer). Pour into 2 plastic quart containers, leaving at least an inch of room at the top, and freeze over night.
To assemble: Remove the frozen quart container from the freezer and, using a spoon, shave it and scoop into a glass. Then add a shot of gin or vodka to the glass, plus enough soda water to cover the slush. Stir until everything is combined and the drink has a slurpee-esque consistency. Add a straw, garnish with a lime if desired, and serve. This recipe should make about 12 generous servings.
