Our country has a vast territory and rich resources, and there are many kinds of traditional food. Among them, there is one delicacy that especially embodies the flavor of the New Year in winter, and that is sausage. I believe that all friends, as long as they are not vegetarians, have eaten sausages. And for those who have not experienced the era of making sausages by themselves, they may have a doubt, that is, what is the thin coating on the outside of sausages? Something, could it be a rubber product? In fact, the thin coating on the outside of sausage is casing, which is usually pig intestine. In some places, sheep intestine is also used. Let’s learn about it with the editor.

Sausage is generally called in the south. In the north, it is actually called five-sausage sausage, but the production method is basically the same. The only difference is that the sausages in the south are mainly sweet and spicy, while the five-sausage sausages in the north are salty. Lord. Sausage is made by marinating fresh pork, then filling it into casings and hanging it to dry. The cooked sausage can be stored for a long time because the moisture has been removed, and it tastes delicious. The making of sausage should be an excellent method created by the ancients to preserve meat, because there were no refrigerators or freezers in ancient times, and sausage can preserve the quality of meat very well. Although every household now has a refrigerator, the delicious taste of sausages encourages people to still enjoy making sausages even after the winter comes. Sausages represent the taste of the New Year.

The production of sausages definitely requires the use of casings, which are usually made from pig intestines. I remember when I was a kid, every year after winter, my family would make their own sausages, put the casing on a water spout, stuff the marinated meat into the casing along the water spout, and carefully drive the meat to the bottom of the casing. But this process must be done slowly and don't be impatient, because if you are not careful, the casing may be burst. After the casings are filled, tie them into sections and hang them in a ventilated place.

With the advancement of science and technology, in addition to the casings made from natural animal intestines, there is also an artificial casing. Artificial casings refer to artificially synthesized collagen casings, which can also be eaten normally.
