Yuenyeung (Chinese: 鴛鴦, often transliterated according to the Cantonese language pronunciation yuenyeung, yinyeung, or yinyong), yuanyang (in Mandarin), coffee with tea is a popular beverage in Hong Kong.
The drink is made from a mixture between coffee and tea. According of Hong Kong's Leisure and Cultural Services Department, the mixture is three parts coffee and seven parts Hong Kong-style milk tea, it can be served hot or cold. However, the way in which it is made can vary from vendor and region.
It was originally served at dai pai dongs (open air food vendors) and cha chaan tengs (café), but is now available in various types of restaurants.
The name yuenyeung, which refers to mandarin ducks (yuanyang), is a symbol of conjugal love in Chinese culture, as the birds usually appear in pairs and the male and female look very different. This same connotation of a "pair" of two unlike items is used to name this drink.
A Hong Kong dai pai dong-style restaurant called Lan Fong Yuen (蘭芳園) claims both yuenyeung and silk-stocking milk tea were invented in 1952 by its owner, a Mr. Lam. Its claim for the former is unverified, but that for the latter is on the record in the official minutes of a LegCo council meeting plausibility.
During the summer of 2010, Starbucks stores in Hong Kong and Macau promoted a frappuccino version of the drink. It was sold as the "Yuen Yeung Frappuccino Blended Cream".
There is a caffeine-free variant of yuenyueng, called children's yuenyeung (兒童鴛鴦). It is made of Horlicks and Ovaltine, both of which are common in cha chaan tengs in Hong Kong.
