263. Pan-American Cocktail

My interpretation:
  2 oz Rittenhouse Rye (or if it’s too woody for you, Old Granddad)
  1 dash gum syrup
  1 dash lemon juice

Shake (20 seconds), strain into cocktail glass, serve. — This drink, not named for the Pan-American Airways (which existed from 1927 to 1991) but rather for John Barrett’s association of all (North and South) American countries, as we are told in the Old Waldorf Bar Book, appears first in Straub 1913 before showing up in JM 1916. The Old Waldorf calls for a half lemon muddled and three dashes of syrup. At any rate, your dash should be substantial enough to be noticed in this liquor-forward whisky service, and yet not result in a Whisky Sour. The emphasis here is only on smoothing the whisky.
