Note: The most important thing for the scallion cake is to make the dough completely. Generally, it takes 3 hours to make the dough completely and make the taste of the scallion cake crisp.
1, first of all, the yeast powder should be melted with warm water of about 35℃, so as not to be assimilated with flour. This step is very important, and the yeast powder should be melted separately to activate yeast activity.
2. Pour the flour into it, add water and mix the dough with force. After kneading the flour into a smooth dough, apply vegetable oil on the surface. Applying vegetable oil can make the flour ferment more completely. The oil can prevent the water from volatilizing, and it also has the function of heat preservation. Cover the dough with plastic wrap and wait for the dough for about 3 hours.
3. At last, the dough is very fermented. You can see that there are many honeycomb holes in the dough. Continue to knead the dough. After the dough is smooth, roll the dough into thin noodles.
4. Finally, sprinkle with chopped green onion and coat with oil, and the scallion cake will be fine.
