To cook a pig's head, use a stainless steel barrel with a diameter of 5 cm.

In the food system, pig's head is usually regarded as a cheap dish, which is sold together with the water and pig's feet. As a cheap food, it is made into sumptuous food and appetizer for the poor, and it is not allowed to be served.

Pig's head is difficult to take care of, and it has a special taste which is generally regarded as bad smell. It is hard to be called a high-grade food material, and it is hard to find traces in famous court dishes in past dynasties. In addition, scholars in past dynasties rarely praise the delicious food cooked by pig's head, so it is difficult to become a famous dish even in local cuisines.

However, there is an exception in Huaiyang cuisine. A famous dish in Yangzhou is called "Three Heads of Yangzhou", in which the whole pig's head is grilled and roasted together with the lion's head and the stewed silver carp's head. The whole pig's head has been grilled and roasted in Yangzhou for hundreds of years. According to the poem "Looking at the South" written by a layman in Baisha Xing 'an in the Qing Dynasty, Yangzhou is good, and fahai temple swims on the lake, leaving the other side empty, and the water tower reflects the middle stream, leaving guests rotten.
