"I love it when one of our regulars asks us to create a cocktail on the spot based on crazy criteria -- and it's even better when we can pull off a decent drink on the first try. One night Avery Glasser, the man behind Bittermens bitters and one of the bar's original regulars, asked me to make him a drink that contained all of his favorite ingredients. The problem was that he likes a lot of weird shit. But I gave it a shot, splitting both the base spirit and its modifiers, and it resulted in a surprisingly balanced drink."
An enjoyable cocktail for some, but for me, the Allspice overpowers. Maybe try a teaspoon instead. This drink has so many overpowering ingredients in it that it's amazing it works at all, but it does to some extent. I just wouldn't go out buying them just to make this.
