Water chestnut cake (traditional Chinese: 馬蹄糕; simplified Chinese: 马蹄糕; Cantonese Yale: máhtài gōu) is a sweet Cantonesedim sum dish made of shredded Chinese water chestnut. When served during dim sum, the cake is usually cut into square-shaped slices and pan-fried before serving. The cake is soft, but holds its shape after the frying. Sometimes the cake is made with chopped water chestnuts embedded into each square piece with the vegetable being visible. One of the main trademark characteristics of the dish is its translucent appearance.
It is one of the standard dishes found in the dim sum cuisine of Hong Kong, and is also available in select overseas Chinatown restaurants.
