From Spirit Savvy
Makes 10-12 pops
1/4 cup mint simple syrup (see below)
5 cups of watermelon (seeds removed)
Juice of three limes
1 capful of balsamic vinegar (this intensifies the watermelon flavor)
1/3 cup tequila
To make the simple syrup, mix equal parts sugar (1 cup) and water (1 cup), add about 1/2 cup of shredded mint and heat until sugar dissolves. Let the mint steep in the cooling water for about an hour and strain. Reserve the mint. Put mint, lime juice and watermelon in a blender and blend to crush the watermelon. (I like it with some chunks of watermelon still visible.) Add simple syrup, vinegar and tequila. Fill your molds and place in freezer for about an hour, then add the sticks (so they’ll stand up better). Freeze for at least 24 hours before serving.
