Mianwo
Mian wo is a deep-fried doughnut-shaped snack from Wuhan in Hubei province in central China. It is made from soy milk, rice milk, flour, sesame and chopped scallion. Mian wo usually has a salty taste, but a sweeter variant may be made with diced sweet potato.
The history of this food is unknown; some believe it has been made since Qing Dynasty by a local sesame cake maker, Chang ZiRen.
