This is my overall favorite cocktail. I use 2 1/2 oz. Rye (Redemption is good), Punt e Mes, and 1/4 oz. Cherry Heering. Absinthe should be a rinse not stirred in. Leave a small pool in the bottom of the glass. A dash of aromatic bitters doesn't hurt it either.
Stirring counter-clockwise will ruin this one. ;-)
