If we want to ferment flour, we should first prepare a proper amount of dry yeast, then pour the dry yeast into warm water to melt, then mix the yeast water with flour and add a proper amount of water until it is kneaded into dough.

After we knead the flour into smooth dough, we can prepare a container and put the dough in it, and then seal the dough with plastic wrap until it expands to twice its original size. After the above steps are completed, the dough is fermented successfully. At this time, we just need to take out the dough and knead it for a while, and then we can continue to use it to make steamed bread, steamed buns, rolls and other foods.
