Cooking Steps

1. 

   Step1:Because it's so simple, I took a picture of the steps. The leftmost is the collection of all the spices in my family. Put them in the feed bag together with scallion and ginger to seal the mouth. You don't need to worry too much about the variety of seasoning. You don't need too much of each. In the middle is the protagonist, Niu tenden. The cold water pot is boiled in advance. On the right is three year old brine. Keep one can at a time. Freeze. Defrost in advance when necessary.

   Step2:Put the above three parts into a pressure cooker and cook for 50 minutes. Don't open the lid. Soak them overnight and take them out for slicing.
