2. Boil brown sugar with water until the sugar melts, then cool to about 40℃.

3. Add a little warm water to the yeast and stir to melt. Set aside.

4. Add brown sugar water to the powder and stir until there are no particles.

5. Add the yeast water to the slurry and stir evenly. Just lift the slurry into a streamlined state. If it is too thin, add some powder. If it is too thick, add some water. Ferment for 30 minutes. There are a lot of bubbles in the fermented batter, stir evenly to release air. Brush oil on the bottom of the plate, pour the batter into it, shake out big bubbles, put cold water into the pot and steam for 25 minutes.
