This is my very first cocktail I ever created. It's a spin on an aviation using rum.
1.5 oz. Flor de Caña 7yr Blanco rum
0.5 oz. Crème de Violettes
0.5 oz. lime juice
Barspoon of simple syrup
1 small egg white
1 dash of Angostura bitters (optional)
Add all ingredients except Angostura butters into a shaker tin, and hard shake for 30 seconds. Add a hand full of ice cubes and shake again for 10 seconds. Then fine strain into a chilled coupe glass. (Optional- Float a dash of Angostura bitters on top).
