Combine lime juice, simple syrup, mint leaves and lime zest in a pitcher; using the handle of a long wooden spoon, lightly crush the mint and zest. Add ice cubes and sparkling water; stir to mix well. Divide among 4 glasses; garnish with lime slices and mint sprigs, if desired.Advertisement
Tip: To make your own simple syrup, bring 1 cup sugar and 1 cup water to a boil in a medium saucepan, stirring frequently to dissolve the sugar. Let cool for 30 minutes and then refrigerate until cold, at least 1 hour. Simple syrup can be stored in the refrigerator, covered, for up to 6 months.
