Yah,the Douhua is a kind of breakfast usually eaten by the eastern parts of China ,while the southerner perfers to service it as a dessert or snack for the breaktime.
I used to have Douhua with shengjian or xiaolongbao or Cifantuan quite often during the past time,say we can still see many small breakfast inn.But now most of the little booths are replaced by noshery-chain
.
In Taiwan, douhua is served with toppings like cooked peanuts, azuki beans, cooked oatmeal, tapioca, mung beans and a syrup flavored with ginger or almond. During the summer, douhua is served with crushed ice; in the winter, it is served warm.
In Hong Kong it is known as bean curd dessert, or by the name dau fu fa (豆腐花) in Cantonese. There, it can be served with ginger or syrup, and sometimes as a mixture with black sesame paste, and sometimes also with coconut milk. Traditionally it is made with wooden bucket, which is sold as dau fu fa in wooden bucket (木桶豆腐花). Dau fu fa is also sold as packed cold dessert at supermarkets.
Guangdounese have these kind of dessert for hundreds of years while the people in northern China
eat douhua with soy sauce as a breakfast , thus making a salty flavour.
As in my hometown we usually have salty douhua plus a plate of shengjian baozi or a steamed boxs of xiaolongbao- a rich breakfast.
Of course we eat those as a breakfast set out ,but you can still make it at your home.
