A herbal and sour aperitif & bitters cocktail ∙ Dry shake ∙ 5 min ∙ 13.7% ABV ∙
The Angostura Sour is a sour that uses 45 ml of Angostura aromatic bitters as its base instead of a spirit, shaken with lime, sugar and egg white.
The Angostura Sour traces back to a recipe called the Angostura Fizz, also known as the Trinidad Fizz, that spirits writer Charles H. Baker Jr. recorded in his 1939 book The Gentleman's Companion, Volume II, describing it as a stomach remedy from the humid shores of Trinidad. Baker's recipe was unusual for using Angostura bitters as the drink's base rather than as a seasoning.
In 2009, New Orleans bartenders Kirk Estopinal and Maksym Pazuniak, both working at the bar Cure, revived and reworked Baker's formula as the Angostura Sour for their self-published cocktail pamphlet Rogue Cocktails, keeping the bitters-as-base concept while giving it a modern sour treatment. The related Trinidad Sour, which adds rye whiskey and orgeat, appeared around the same time and became the better-known drink built on the same bitters-forward idea.
