Hummer is a creamy ice cream cocktail that was concocted in Detroit in the 1960s. Often dubbed as an adult milkshake, the cocktail consists of ice cream, white rum, and Kahlua liqueur. The ingredients are blended with ice, and the drink is poured into a tall, chilled glass.
It should have a thick and creamy consistency. Jerome Adams from the Bayview Yacht Club is mostly credited as the inventor, and the name allegedly stems after one customer commented that drinking two of these boozy cocktails made you want to hum. The cocktail was initially popularized among the sailing crews that would visit the Bayview, but it soon became prominent in the entire state.
