The term
hamburger originally derives from
Hamburg, the second-largest city in
Germany; however, there is no certain connection between the food and the city.......As versions of the meal have been served for over a century, its origin remains ambiguous.
[6] The book
The Art of Cookery Made Plain and Easy by
Hannah Glasse included a recipe in 1758 as "Hamburgh sausage", which suggested to serve it "roasted with toasted bread under it". A similar snack was also popular in Hamburg by the name "Rundstück warm" ("bread roll warm") in 1869 or earlier,
[7] and supposedly eaten by many emigrants on their way to America, but may have contained roasted beefsteak rather than
Frikadeller. Hamburg steak is reported to have been served between two pieces of bread on the
Hamburg America Line, which began operations in 1847. Each of these may mark the invention of the hamburger, and explain the name.
There is a reference to a "
Hamburg steak" as early as 1884 in the Boston Journal.[OED, under "steak"] On July 5, 1896, the
Chicago Daily Tribune made a highly specific claim regarding a "hamburger sandwich" in an article about a "Sandwich Car": "A distinguished favorite, only five cents, is Hamburger steak sandwich, the meat for which is kept ready in small patties and 'cooked while you wait' on the gasoline range
Personally not into predigested meat mush. Prefer a real steak
