Fill your glass of choice with ice (I prefer a wine glass)
Gather your clean mint leaves and place them on one of your hands, slapping them once with the other hand (This allows the essential oils in the leaves to release and add more flavor to your cocktail)
Pour the elderflower liqueur over the ice and mint leaves
Add the Prosecco and top with sparkling water
Add your lime slices for a garnish
Give it a slight swirl with a cocktail spoon
Enjoy Immediately!
