Corpse Reviver #1
Corpse Revivers were (and are) a style of drink intended for a bit of the hair of the dog (an expression that refers to alcohol used as a treatment for a hangover). Hard to say exactly what it was about these drinks that made them seem more appropriate for this use over other drinks. Regardless of time of day of consumption, the Corpse Reviver #1 is worth discovering as it is not seen very often.
2 oz brandy
1 oz sweet vermouth
1 oz applejack
