Yuanyang — yuenyeung in Cantonese — is a mixture of coffee and Hong Kong-style milk tea, served hot or iced.
The name
Mandarin ducks, which in Chinese symbolism are always seen as a pair and are noted for the male and female looking completely different. The name signals two unlike things joined.
What goes in it
Hong Kong milk tea: strong black tea, traditionally brewed through a cloth “sock” filter, with evaporated milk and sugar.
Strong brewed coffee, similarly prepared.
Mixed roughly three parts coffee to seven parts tea, or the reverse — proportions vary by shop and there is no standard.
Why it works
Tea tannins and coffee bitterness are structurally similar, and evaporated milk plus sugar carries both. The result is heavier and more aromatic than either alone, with tea’s astringency cutting coffee’s roundness.
Where you drink it
Cha chaan teng — Hong Kong tea restaurants — where it is a staple alongside pineapple buns and instant noodles. It appears across the Cantonese diaspora.
Making one at home
Brew strong black tea and strong coffee separately. Combine, add sweetened condensed or evaporated milk and sugar, and adjust the ratio to taste.
Iced, over plenty of ice, is the summer form.
