How to make steamed bread soft?

The method of making soft dough steamed bread is as follows:

1. Activate yeast: put the yeast powder into a container, add a little warm water, stir until it melts, and let it stand for 3-5 minutes before use.

2. Adjust the water temperature: the temperature is between 28 and 30 degrees.

3. Ratio of flour to water: The water content of 500 grams of flour shall not be less than 250 ml, which is approximately equal to the ratio of 2: 1.

4. Dough treatment: After the flour is mixed with yeast and water, it should be fully kneaded to make the flour and water fully combined as far as possible.

5. Fermentation conditions: The optimum environmental temperature for fermentation is 30-35 degrees, preferably no more than 40 degrees, and the humidity is 70-75%.

6. Secondary fermentation: This is a very important process, which is related to the softness of the finished dough. Put the dough on the panel, knead out the air in the dough, then put it in a relatively sealed container and let it ferment at room temperature for about 30 minutes.
