Sherwin Noel’s Rum Punch

In a tall, ice-filled glass, combine 1–1½ oz dark rum (such as Clarke Court’s Special Dark) and ½–1 oz overproof rum (such as Jack Iron) with ½ oz sugar syrup. Fill with a blend of fruit juices (Noel uses grapefruit, orange, pineapple, sour orange, and lime) and add a couple shakes of grenadine and Angostura bitters. Stir and grate fresh nutmeg on top.
