Ham was invented in the Song Dynasty. The early occurrence of the word ham was in the Northern Song Dynasty. Su Dongpo clearly recorded the method of ham in his "Ge Wu Ruo Tan · Diet", "The ham is cooked with two pig pancreas, and the oil is removed. The ham is hidden in the valley. It’s not oil for decades. It’s a cloud of chaff." Ham is a famous specialty of Jinhua, Zhejiang. The famous anti-gold general Zongze is a native of Yiwu, Jinhua, Zhejiang. He once brought the pickled pork leg from his hometown to Song Qinzong, salted pork leg. The flesh color, fragrance, and taste are complete, because the color is bright red like fire, Song Qinzong gave the name "ham", and the ham has become a tribute ever since. The hams are all pork hind legs. Jinhua ham should have been made from the hind legs of Jinhua two-headed black crocodile, but since the two-headed black crocodile is almost extinct, the modern standard ham should be the ordinary salty leg as the raw material (that is, the leg cured in salt in the cold storage). The production of ham requires multiple processes. The rich minerals and protein in ham are not only mouth-watering and delicious, but also a tonic for strengthening the body. Jinhua, Dongyang, Lanxi, Yiwu, Wuyi, Pujiang, and Yongkang are rich in ham. These places belong to Jinhua and are collectively called Jinhua ham. At one time, Lanxi had the most, but now it is Dongyang. So far, Jinhua ham from Zhejiang, China is not only sold domestically, but also exported to Europe and the United States. It still exudes its unique huge alluring charm for thousands of years.
