Too many and you're in it! This is a punchy, spirit-forward cocktail that was apparently created as a pick-me-up but is perhaps better suited as a (put-you-down)...
This one's delicious (reminds me distantly of a Preakness Manhattan); the three ingredients really bring out one another's spicy qualities, from the peppery bite of the rye to the subtler, sweeter herbal spice of the liqueurs. Could see it working well in a range of proportions, from heavier on the liqueurs to a drier mix.
