The historical origin of hamburgers:

1, it turns out that hamburgers are patties made of minced beef and flour, so they are called beef patties. People in Hamburg, Germany, improved it by kneading chopped beef sauce in flour, spreading it into cakes, frying it and eating it, so they named it Hamburg after the place. 19th century? German immigrants brought the cooking skills of hamburger patties to the United States.

2. 1932 Some people put this fried beef pie into steamed buns sprinkled with sesame seeds as a staple food or snack. Later, it was renovated and gradually merged with sandwiches. The beef patties were sandwiched between two buns, which were called hamburgers.

The name Hamburg comes from Hamburg, a city in the northwest of Germany. Today, Hamburg is the busiest port in Germany. In the middle of19th century, people living there liked to mash steaks into specific shapes. This way of eating may have been spread to the United States by a large number of German immigrants at that time.
