This cocktail was recently featured on Cocktail College podcast. so I made to that spec. 2.5 oz Jack Daniel Bottled in Bond Rye, 1 bar spoon Absinthe, 1 bar spoon rich simple syrup, 2 dashes of Angostura. Lemon twisted expressed over the top. Served in an Old Fashioned glass over a big cube (stirred in a mixing glass and strained). Truly superb. 100% will have this again.
