1 and 1/2 sticks lemongrass, cut into 1/4-inch pieces
Juice of 2 limes
1 and 1/2 teaspoons simple syrup, or to taste (recipe below)
1 paper-thin slice of peeled fresh ginger
2 ounces Tanqueray No. Ten gin
2 ounces club soda
Place lemongrass, lime juice, simple syrup, and ginger in a food processor, and purée. Allow to rest for 30 minutes. Pass purée through a fine strainer. Pour the juice into a shaker filled with ice, and add the gin. Shake well. Strain into a glass filled with ice, dilute with club soda, and stir to incorporate.
To make simple syrup:
Combine 1 cup granulated sugar and 1 cup water in a saucepan. Bring the mixture to a boil for a few seconds. Set aside to cool.
