Place mint leaves and the juice of ¼ of a lime into a stemless wine glass. Muddle the mint to release some of its oils.
Fill the glass halfway with ice cubes.
Pour in the elderflower liqueur and club soda.
Add 3 slices of lime then top off the glass with prosecco. Stir gently and serve immediately.
Notes
Mocktail VersionSwap out the prosecco for non-alcoholic sparkling white wine, lemon-lime seltzer, or sparkling fruit juice. Use elderflower syrup instead of liqueur for a refreshing virgin Hugo Spritz!
