There is more to rum than frozen Daiquiris and Piña Coladas. A nationwide tiki renaissance finds modern bartenders exhuming sugary archives and elevating rum drinks into inventive offerings well worth seeking out. One of the more interesting combinations is rum and Aperol, the classic Italian amaro. Autumn in the Tropics is a mix of rum, Aperol, lemon, and just enough pineapple juice to give the drink a signature foam. Muddled blueberries and a fiery squash blossom put a Northeastern twist on the Caribbean spirit. The resulting drink provides a tropical taste of summer mixed with the flavors of the northern U.S., just as the leaves start to change color.
