Yuanyang is a drink that combines coffee and tea. It typically consists of three parts coffee and seven parts black milk tea—a combination of water, black tea leaves, and either sweetened condensed milk or evaporated milk and sugar.
This coffee-tea combination originated in Hong Kong, where it is commonly sold by street vendors. Each vendor usually has a signature recipe that may differ in the choice of coffee and the proportions of both beverages. The name yuanyang (which refers to mandarin ducks) was given as a poetic reference because the ducks represent a symbol of conjugal love in which opposites attract.
