Amaretto Sour (Morgenthaler Style)
Jeffrey Morgenthaler rehabilitated the maligned Amaretto Sour in 2012 by adding a small amount of cask-strength bourbon and egg white. The bourbon provides dryness and backbone that balances the sweetness of amaretto; the egg white gives it a gorgeous texture and foam. This version uses Amaro Averna as a richer, more complex base. Use Wild Turkey 101 for the bourbon — the high proof holds up.
