Hamburg steak

Immigrants to the United States from German-speaking countries brought with them some of their favorite foods. One of them was Hamburg Steak. The Germans simply flavored shredded low-grade beef with regional spices, and both cooked and raw it became a standard meal among the poorer classes. In the seaport town of Hamburg, it acquired the name Hamburg steak. Today, this hamburger patty is no longer called Hamburg Steak in Germany but rather "Frikadelle", "Frikandelle" or "Bulette", originally Italian and French words.

In the late 18th century, the largest ports in Europe were in Germany. Sailors who had visited the ports of Hamburg, Germany and New York, brought this food and term "Hamburg steak" into popular usage. To attract German sailors, eating stands along the New York city harbor offered "steak cooked in the Hamburg style". The Oxford English Dictionary

defined Hamburg steak as salt beef. It had little resemblance to the hamburger we know today. It was a hard slab of salted minced beef, often slightly smoked, mixed with onions and breadcrumbs. The emphasis was more on durability than taste.

Invention of meat choppers

during the 19th century. The meat grinder was purportedly invented by Dr. Karl Drais

 in the 19th century. Patents were filed for some designs that were interpreted as meat choppers.
  • E. Wade received Patent #x5348 on January 26, 1829 for what may be the first patented "Meat Cutter." The patent shows choppers moving up and down onto a rotating block.
  • G. A. Coffman received Patent #3935 on February 28, 1845 for an "Improvement in Machines for Cutting Sausage-Meat" using a spiral feeder and rotating knives something like a modern food grinder.

Restaurant menus

The first printed American menu which listed hamburger was an 1826 menu from Delmonico's in New York.

Between 1871-1884, “Hamburg Beefsteak” was on the “Breakfast and Supper Menu” of the Clipper Restaurant at 311/313 Pacific Street in San Fernando. It cost 10 cents—the same price as mutton chops, pig’s feet in batter, and stewed veal. It was not, however, on the dinner menu, only “Pig’s Head” “Calf Tongue” and “Stewed Kidneys” were listed.

Hamburger Steak, Plain and Hamburger Steak with Onions, was served at the Tyrolean Alps Restaurant at the 1904 St. Louis World's Fair.
Cookbooks


By the mid-18th century, German immigrants also began arriving in England. One recipe, titled "Hamburgh Sausage," appeared in Hannah Glasse's 1758 English cookbook called The Art of Cookery Made Plain and Easy. It consisted of chopped beef, suet, and spices. The author recommended that this sausage be served with toasted bread. Hannah Glasse's cookbook was not published in the United States until 1805. This American edition also contained the "Hamburgh Sausage" recipe with slight revisions. In addition, the original Boston Cooking School Cook Book, by Mrs. D.A. Lincoln (Mary Bailey),
1844 had a recipe for Broiled Meat Cakes and also Hamburgh Steak. Moreover, the 1894 edition of the book The Epicurean: A Complete Treatise of Analytical & Practical Studies contains a listing for Beef Steak Hamburg Style.
The dish is also listed in French as Bifteck à Hambourgeoise.
