Step 1

Put two martini glasses into the freezer or fill them with ice and set them aside. Cut four passion fruit in half and scoop the seeds into a sieve set over a small bowl. Press down on the seeds with the back of a spoon to extract the juice.

Step 2

Add the passion fruit juice, vanilla vodka, Passoa and lime juice to a cocktail shaker.

Step 3

Fill the shaker up about halfway with ice, put on the lid and shake for at least 30 seconds to ensure a proper mix.

Step 4

If your shaker doesn't have a built-in strainer, put a coiled strainer over the top of your shaker and strain into the chilled martini glasses (don't forget to dump the ice out of the glasses first!) Garnish with a piece of fresh passion fruit.

Step 5

Pour a measure of prosecco into two shot glasses and serve alongside the Pornstar Martini.
