Mantou is a type of plain steamed bun that originated in China. The buns are made with a simple dough consisting of flour, yeast, sugar, and water. They are steamed until they become soft and fluffy, with a slightly sweet taste. Mantou can be enjoyed on its own or used as a base for other dishes, such as braised meats or stir-fried vegetables. It is a versatile and comforting food that is popular in many Asian cuisines.
