Frozen Rock Star Martini

How to make the Rock Star Martini even more delicious?
1. In a blender, mix ice, a measure of Passoã, another of vodka, a dash of vanilla syrup, the juice from half a lime, and the pulp of half a passion fruit. Don’t stop until it gets its slushy consistency!
2. Serve immediately in a fancy pre-chilled glass, and decorate with the other half of the passion fruit (for nibbling on later).
3. Follow with a shot of prosecco or champagne straight after.
