The best way to get to know Sarah Rosner is to try one of her imaginative cocktails from the new Washington, D.C. bar, Radiator, located in the popular 14th Street corridor.
A Hawaiian native, this lead bartender puts a unique twist on the modern cocktail menu with libations that are part-classic, part-Hawaiian and all-Sarah. The Rickey Goes to Hawaii exemplifies this creativity and pays homage to Sarah’s South Kona upbringing by adding li hing powder to this classic cocktail. Another must-have recipe for summer sipping is the Fancy Pants–a.k.a. Sarah’s self-proclaimed “improved champagne cocktail”–which is a beautiful medley of gin, sparkling wine, maraschino, absinthe, bitters and tarragon. Cheers and aloha!
Rickey Goes to Hawaii
A unique variation on the Rickey – Washington D.C.’s Native cocktail – this version speaks to Sarah’s Hawaiian roots. Li hing powder has a sweet-sour-umami flavor and is widely used in Hawai’i, especially in gummy candy and popcorn.
