Bai ye

Tofu skin, yuba, fupi, beancurd skin, beancurd sheet, or beancurd robes is a food item made from soybeans. During the boiling of soy milk, typically heated to 80–90 °C, in an open shallow pan, a film or skin composed primarily of a soy protein-lipid complex forms on the liquid surface. The films are collected and dried into yellowish sheets known as tofu skin. Since tofu skin is not produced using a coagulant, it is not technically a proper tofu; however, it does have a similar texture and flavor to some tofu products.
