Cocktail Boothby's American Bar-Tender by Wm. T. Boothby (1891, p.27)

  1. Hold a teaspoon containing a sugar lump saturated with yellow Chartreuse over a cup of hot black coffee.
  2. Set the sugar aflame, let it burn until dissolved into the coffee, mix, and serve.

This is a good example of after-dinner theatrical service outside the formal cocktail families.

The drink is defined by flaming the liqueur-soaked sugar directly over the coffee.

Ice: Frapped semi-frozen service

This keeps a frapped coffee-and-brandy after-dinner service visible alongside the hotter and more flamboyant cafe-royal traditions.

The semi-frozen texture is the whole point of the service and should not be flattened away.

Sheridan says the drink is very potent.
