1 1⁄2 oz Gin, Hendrick's
1 oz Lime juice
1⁄2 oz Herbal liqueur, Green Chartreuse
1⁄2 oz Simple syrup
2 ds Bitters (Homemade - Forest Floor Bitters*)
1⁄4 oz Absinthe, Germain-Robin
Instructions
In a shaker, add first five ingredients over ice and shake. Strain into glass, drip absinthe into cocktail so that it louches.
Notes
Sorry about the impossible to find bitters - I made them, and they're pretty good for a first try, and yes, they taste like forest floor. Boker's is a fair substitute, but it has more coffee aroma and flavor.
