A 1920s gin sour with a lurid backstory: London dry gin and fresh orange juice are shaken with grenadine and a measure of absinthe, the herbal anise riding under the citrus and the pomegranate sweetness. Harry MacElhone published it at his Harry's New York Bar in Paris (Frank Meier of the Ritz also claimed it), naming it for Serge Voronoff's discredited monkey-gland rejuvenation surgeries then making headlines.
