Hamburger, also known as hamburger, is known as one of the five western fast food. The word Hamburger is the Chinese name of English hamburger, which contains transliteration and free translation, and is sometimes called hamburger directly. The original name of Hamburg comes from the German city of Hamburg. In English, Hamburger means "from Hamburg", which can refer to the hamburger itself or the patties made of ground beef or other ground beef in the bag. At present, this kind of meat pie is generally called hamburger steak in Chinese, while hamburger is used to refer to a round sandwich with hamburger steak. The original hamburger was a meat pie made of ground beef and flour, so it was called beef patties. In ancient times, Tatars had the habit of eating beef raw. As the Tatars moved westward, they were introduced to the Balkans and then to Germany, gradually turning raw food into cooked food. 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 "hamburger patties" after the name of the place. From 65438 to 0850, German immigrants brought the cooking technology of hamburger patties to the United States. 1932 Some people put this fried beef patties into steamed buns sprinkled with sesame seeds as staple food or snacks. Later, after renovation, it gradually merged with sandwiches, and the beef patties were sandwiched in a bun that was split in two, hence the name Hamburg, which means hamburger with bread. The name Hamburg comes from Hamburg, a city in northwest Germany. Today, Hamburg is the busiest port in Germany. /kloc-In the middle of the 0/9th century, people living there liked to mash steaks into certain shapes, which may have been spread to America by a large number of German immigrants at that time. 1836, a dish named "hamburger steak" appeared on the American menu; As can be seen from a cookbook 1902, the practice of hamburger steak at that time was very close to the concept today, that is, ground beef and onions were mixed with pepper. In the late 20th century, Americans improved the practice of hamburger steak and sent it to fast food restaurants, which is the origin of today's favorite hamburger. In addition to "hamburger", hamburger also means "ground beef, beef pie", which shows that hamburgers are mostly made of beef. However, various types of hamburgers, such as pork chop, fish flavor and chicken, were introduced one after another, so it was impossible to eat all the food at once by relying on beef under visible light. It is worth mentioning that because hamburger is a kind of minced beef pie, people also use it as a metaphor for "a boxer who was beaten black and blue". There is a saying in American slang that "beat someone up and beat them into patties". In the1980s, with the popularity of American fast food chain McDonald's in Asia, the Chinese word hamburger has become synonymous with all sandwiches made of steamed buns. The practice and ingredients of Asian hamburgers vary from region to region: there are usually cut buns with various ingredients and sauces in the middle. In addition to the most typical beef patties, lettuce, tomato slices, onions and pickles, there are different choices such as pineapple, pork patties and seafood. On the other hand, hamburgers are still one of the standard recipes in restaurants outside Asia. Many Asians are used to eating hamburgers only in fast food restaurants. It is strange to spend more than ten dollars on a hamburger in a restaurant, because it is not worth it. But westerners regard it as a general dish. In recent years, in addition to traditional beef patties, butter, mustard, tomato sauce, salad dressing and so on. The second layer is coated on the round bread, followed by food such as tomato slices, onions, vegetables and pickles. Can be eaten at the same time. This kind of food is convenient to eat, delicious and comprehensive in nutrition, and has now become one of the convenient staple foods in the world. But according to many people who know the foreign food industry, there are two main forms of hamburger food in western countries. One is hot hamburgers sold by fast food chains like McDonald's and KFC. The other is frozen hamburgers, which are sold in the freezer of the food store. After customers buy home, they will eat it after heating it in the microwave oven. Just like the packaged hamburger we bought in supermarkets, chain stores or stalls, it can be said that it is a kind of hamburger food with China characteristics.
