Del's frozen lemonade is most associated with which U.S. state?

Del’s frozen lemonade is most associated with Rhode Island.

Del’s is a frozen lemonade brand strongly identified with Rhode Island, where the drink is a familiar summer tradition. Its product is a lemon-flavored slush made from water, lemon juice concentrate, and real lemons, typically dispensed from a specialized machine.

The company’s origin story begins with Angelo DeLucia, whose father, Franco, brought a lemonade recipe from Italy to the United States. Angelo developed a machine for serving the frozen drink, and the first Del’s stand opened as a pushable cart in Cranston, Rhode Island, in 1948.

Del’s later became especially visible through mobile trucks and seasonal stands. It is also common in southeastern Massachusetts, but Rhode Island remains its defining home. In 1993, Del’s lemonade even competed to become Rhode Island’s official state beverage; coffee milk ultimately won that designation.
