Ginger Mojitos for a Crowd

1. 1In 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 1 hour.
2. 2Place a fine-mesh strainer over a 1-1/2- to 2-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.

To serve:

1. 1For 1 drink, fill a 10-ounce glass with ice. Add 1/2 cup of the Mojito base, top with 3 tablespoons of the club soda, and stir to combine. Garnish with a mint sprig.
