Ginger Mojitos for a Crowd

In a small saucepan, bring the sugar, water, and ginger to a boil over high heat, stirring to dissolve the sugar, about 5 minutes. Remove from the heat, add the mint leaves, stir to combine, and let cool to room temperature, about hour.

Place a fine-mesh strainer over a 1-1/- to -quart container and strain the syrup, discarding the solids. Add the rum and lime juice and stir to combine. Cover and refrigerate until well chilled.

For drink, fill a 0-ounce glass with ice. Add /2 cup of the Mojito base, top with 3 tablespoons of the club soda, and stir to combine. Garnish with a mint sprig.
