Ham and sausage are essentially two different foods, because their nutritional value and the process of making raw materials are different. For example, first of all, let's introduce ham, which is different in the process of making them. It is a meat food made by curing or smoking the legs of some animals, such as beef legs, lamb legs and chicken legs. It has a long history in China and was eaten as early as the Tang Dynasty. Then sausage is also a common food in our daily life. For example, we can see him among street vendors. He uses very old biotechnology to produce and preserve meat. Chop up animal meat and pour it into casing to make cylindrical tubular food, which has high nutritional value and a long history.
Simply put, ham is made of whole pig thighs, such as some legs of lamb or ox, and sausages are made of minced meat and some seasonings. They also taste different. Ham tastes like bacon, sausage tastes more like meat, and its nutritional value is different. For example, some of my friends' starch and protein contain some vitamins.
That's the difference between ham and sausage. Although they are all meat foods, there are still great differences. Their manufacturing techniques and tastes are different. After the introduction, I believe everyone has a certain understanding of the two foods and can distinguish them correctly.
