I wanted to try something unusual, and this cocktail really fits the bill. I confess up front that I have not tried Becherovka, and from the description of it, I thought that Allspice Dram might be a good substitute. The result was that the Allspice overpowered the mix. I'll try again when I put my hands on some Becherovka, and then I can make a more informed comment on this cocktail.
