Amaretto Sour

The Amaretto Sour in its classic form dates to the 1970s American bar culture, when amaretto first gained popularity in the United States. The rehabilitation was Jeffrey Morgenthaler at Clyde Common, Portland, Oregon, 2012, when he published his recipe with the bourbon addition and egg white technique. The resulting drink's viral success through cocktail blogs reset the drink's cultural reputation.

The Amaretto Sour is the cocktail that Jeffrey Morgenthaler at Clyde Common in Portland rescued from decades of mediocrity — amaretto liqueur, fresh lemon juice, and crucially, egg white and cask-strength bourbon, creating a drink with the silky foam of a Boston Sour and the depth that pure amaretto alone cannot provide. The conventional Amaretto Sour (amaretto plus sour mix) is one of the most maligned cocktails in bar culture; Morgenthaler's 2012 recipe is one of the most celebrated rehabilitations in cocktail history. The addition of bourbon is not mixing bourbon and amaretto — it is adding structural complexity and alcoholic backbone to an ingredient (amaretto at 28% ABV) that lacks the strength to hold a sour together on its own.

• Amaretto's almond-cherry distillate connects to the Italian tradition of marzipan confections, the Spanish turron (nougat with almonds), the French frangipane (almond cream filling), and the Middle Eastern tradition of rose water and almond confections. The almond flavour appears across Mediterranean and Middle Eastern baking cultures as a signal of celebration and richness.
