Bánh bò

Bánh bò is a sweet, chewy sponge cake from Vietnam. It is made from rice flour, water, sugar, and yeast, and has a honeycomb-like appearance (called rễ tre, literally "bamboo roots," in Vietnamese) on the inside due to the presence of numerous small air bubbles. Coconut milk is also usually a part of the batter, imparting a slight flavor and aroma of coconut. The cake is of Southern Chinese origin, although the Chinese version, called bái táng gāo (白糖糕), does not contain coconut milk. Bánh bò are generally eaten as a dessert, although they may also be consumed as an accompaniment to a meal. In the Vietnamese language, bánh means "cake", and bò can either mean "cow" or "to crawl". According to the entry for "𤙭" (bò) in Paulus Huỳnh Tịnh Của's 1895 dictionary Đại Nam quấc âm tự vị, the dessert is named for its resemblance to a cow's udder, implying that the name was shortened from bánh vú bò. However, according to a popular folk etymology, bò refers to how the cake "crawls" up to the rim of the bowl when steamed to completion.
