The key to soft and glittering dough is to put 200 grams of sticky rice flour into a basin, mix 100 grams of fine sugar, slowly pour in clear water, and stir with chopsticks to melt into thick batter, taking care not to have lumps of dough. Prepare a larger steamer, put one-third of the water, and turn the fire down after it boils. Open the lid and be careful not to get burnt by hot air. Put the basin full of batter into the pot, fix the basin with the kitchen clip with one hand and keep stirring with the other.
About 3-4 minutes, the water vapor in the batter evaporates a lot and becomes sticky. When you lift chopsticks, the batter on them will hang up. When this level is reached, take out the basin and continue to stir. Mainly to the bottom of the basin, because of the large heating area, there may be noodles sticking to the bottom of the basin, which should be stirred up with chopsticks. Add a spoonful of warm water of about 40 degrees to 4 grams of yeast powder and melt it. Don't use too hot water, it will burn the active bacteria to death. Pour the melted yeast water into the basin and stir well.
Cover the basin with a wet cloth and ferment for 2 hours. The volume has obviously doubled, and there are many small bubbles in it. It smells a little sour with your nose, that's all. It can be fermented directly in summer. If the weather is too cold, it needs to be fermented at about 30 degrees. Prepare a flat-bottomed steamer with a layer of crude oil on the bottom, which is convenient for demoulding and does not stick to the bottom. Add 5- 10g cooking oil to the batter, stir well, let the bubbles disappear, and pour into the steaming plate.
Reheat the previous steamer, put the steamer in, turn to a small fire after the fire, and steam for about half an hour. Don't lift the lid in a hurry, turn off the fire and stew for 5 minutes, then pour it out and cut it into pieces. White sugar can be changed into brown sugar, which has a different taste.
