Fill a copper mug or cocktail glass with ice. Smack a mint leaf between your hands to release the aroma. Lay it on the ice. Pour the vodka over the mint leaf, followed by the DOLE® 100% Pineapple Juice and ginger beer. Stir briefly with a cocktail stirrer, chopstick, or spoon. Smack the remaining mint leaf, rub gently over the rim of the glass, then use to garnish. Serve immediately.
