【Shandong】Pork buns with onion sauce

Overview

My son's favorite buns.

Mix the yeast powder with warm water and add it to the flour, knead it into a dough and let it ferment in a warm place.
Cut the pork into small cubes and marinate with soy sauce for a while.
Wash and chop the onions, add some salt to remove the water and squeeze out the water.
Put the onions and diced meat into a clean basin. Add oil, sweet noodle sauce, very fresh soy sauce, sugar, salt and chicken essence and mix well to form a filling.
After the dough has fermented, knead it into long strips, cut it into balls, and roll it into cakes.
Take a pie and put the filling in it.
Wrap into buns.
After secondary fermentation, steam it in a pot and boil it for 15 minutes.
The buns are steamed.
