I recently ordered this on a date night at a local restaurant and KNEW I had to recreate it at home. Here is my best attempt and I think you'll be pretty pleased!
2 sprigs of mint leaves
2 parts pomegranate juice, chilled
1 part orange juice, chilled
1 part orange flavored sparkling water, chilled
splash of lemon juice
In a cocktail shaker, muddle mint. Then add other ingredients and shake together. Pour into a martini glass and garnish. Enjoy!
