The yudane is like a small miracle. To get magically soft buns, buns and milk breads, yudane and tangzhong are pretty amazing solutions! I start with yudane, for those hot dog buns. You could also make round hamburger buns. The resulting texture is fantastic and a radical change from a dough made without the yudane. So what is yudane? It is a part of the flour that is mixed with boiling water. This soft, plastic dough is then added to the dough, which then becomes incredible. Why is this? Because the yudan retained water, and caused the starch in the flour to gelatinize. You have to try to believe it!
