1. Combine vodka, cranberry juice, and tripe sec in a small pitcher.  Chill until ready to serve.  Add enough vodka mixture to each champagne flute or other similar sized drink glass to fill halfway.  Add 1-2 teaspoons simple syrup (sweeten to taste) and stir.  Add enough prosecco to fill glass and garnish with cranberries and rosemary sprig.  Cheers!
