1. Make a simple rosemary syrup. Combine the water and sugar in a small saucepan and bring to the boil. Stir until the sugar dissolves. Remove the pan from the heat, add two sprigs of rosemary and let it steep for one hour until cool.
2. Add the gin, lemon juice and one tablespoon of the rosemary syrup to a cocktail shaker filled with ice. Strain into a glass filled with ice and top up with the soda water. Garnish with the lemon slice and remaining rosemary sprig.
