The Harvest Sour is yet another fantastic recipe from Sam Ross, the mixological genius behind the Attaboy and Diamond Reef bars in New York City, and inventor of (probably) at least one of your favorite cocktails.
The Harvest Sour looks to be just a fall-tinged egg sour – but the split base of rye and applejack elevate the flavor tremendously. It’s not in Ross’ original recipe, but we sometimes like to dot the foam with a bit of Angostura or apple bitters for visual appeal and scent.
