A little Campari goes a long way in this cocktail. The combination of gin, Campari, Ginger Rhubarb liqueur and lemon is slightly bitter and very refreshing.
Chill your cocktail glass if you are serving it up, without ice.
Add the gin, Campari, Rhubarb Ginger liqueur, lemon juice and simple syrup to a cocktail shaker.
Add ice to the shaker and shake well, about 15-20 times.
Strain the cocktail into your serving glass, either with or without ice. You can use one strainer, or double strain by passing it through a fine mesh cocktail strainer as well.
Cut a thin piece of lemon peel and twist it over the top of the glass. Add the lemon peel as a garnish and serve.

Notes
Lighten up this cocktail by substituting a low-calorie sweetener for the simple syrup. You can make your own or use a ready made, like this allulose syrup.
