1/3 cup pineapple chunks
4 large mint leaves
2 cups cold sparkling or still water
Put pineapple and mint in a large cocktail shaker. Add 1 tbsp. water; mash well with a muddler or end of a wooden spoon.
Stir in sparkling water, cover, then strain into an ice-filled glass (for a clearer drink, pour through cheesecloth).
