Place champagne flutes or martini glasses in the freezer to chill - you'll want a nice frosted effect on the glass, which will also help keep the drinks especially cold.

Place all ingredients in a medium sized bowl.

With a hand whisk, mix everything together until light and frothy.

Remove your glasses from the freezer and divide the mixture equally among all glasses.

Top with extra Prosecca if desired, stir gently to combine.

Serve immediately in pretty cocktail glasses

Garnish with fresh mint leaves -- optional.
