Rock and Rye is an infusion of citrus fruits and sweetened rye
whiskey. Probably started out in saloons and taverns where some of
the cut fruits at the end of the day were thrown into a jar of
whiskey rather than discarded. Add a little lump sugar, rock candy,
or rock candy syrup, and "Rock and Rye" was born. In the North East
where American Rye whiskey has its deepest historical roots, it
made a great hot drink during cold wet winters. It became popular
enough that certain blends were bottled under proprietary names,
two of which still exist: Jacquin's, and Mr' Boston's. Supposedly,
Southern Comfort hails from the rock and rye tradition, though it
is most likely bourbon based.
At our bar "Rye" in San Francisco, we keep a decanter of our own
Rock and Rye behind the bar. It is made with various Rye whiskeys,
Horehound Rock Candy, Dried Lemon peel, Cassia bark, Clove, Dried
Horehound, and a couple of other secret ingredients.
We serve it as a Rock and Rye Toddy which is two oz. of rock and
rye with 2 oz. boiling water, with a fresh lemon peel. The mixture
is like a whiskey TheraFlu. Tastes great, and the horehound is an
herbal remedy for whooping cough. we also serve it as a base for a
Manhattan recipe which is quite good too.
