Hello, boys and girls. Welcome to our McDonald's restaurant. Do you know how the hamburger came into being? Let me tell you the story while you enjoy the food.
The original hamburger can be traced back to the Middle Ages, when Russians ate raw meat cut into small pieces and formed into patties. This was the first step in a long series of developments that eventually resulted in hamburger as we know it today.
German sailors picked up the raw meat delicacy in their contacts with Russians and brought it back to their home port of Hamburg. But the people there were not accustomed to eating raw meat, so they roasted the outside of the Russian steak; and so the hamburg steak was born.
The hamburg steak was brought to America in the nineteenth century, by German immigrants. Louis Lassen, a cook in New Haven, Connecticut, modified the hamburg steak by sandwiching it between two pieces of bread. But the true American hamburger came into existence in St. Louis, at the Louisiana Purchase Exposition in 1904. A harried cook at the fair quickly slapped broiled beef patties between buns and served them to a demanding crowd, which gulped them down joyously.
At first this new food creation was made from scraps of poorer cuts of meat that were not used for anything else, but before long scraps were not enough. The demand for greater quantities of hamburger could only be met by using the whole cow. Hamburger stands sprang up all over the country, and a side industry of seasoning, such as ketchup and spices, grew up and prospered along with the popular hamburger.
