If you want an example of the sweetness of the Kumquat rind adding that extra dimention to a cocktail then try this St Germain & Kumquat Cocktail. With Gin, St Germain, Kumquats, Sugar Syrup and Soda Water, this is a low ABV and low sugar drink with a beautiful citrusy edge.
In the base of a shaker, muddle together the Sugar Syrup and the Kumquats. Add ice, then Gin and St Germain and shake. Strain into an ice-filled Collins glass, then top with Soda water
