The Pink Moon Sour Next time you get a “surprise me”, do just that with a Pink Moon Sour from Natalie Jacob, author of Mod Cocktails. Combine 2 oz. rum, .75 oz. cherry juice, a splash of fresh squeezed lemon juice, and .75 oz. of honey syrup in a shaker. Add four dashes of ANGOSTURA®Ⓡ Cocoa Bitters and an egg white, and shake until the egg white is frothy. Strain into a coupe glass and wait for the reaction.
