The hamburger is an emblem of the United States. And nevertheless, it originated in Germany and, more precisely, in Hamburg. Since its Mongolian roots, this ground beef has taken on a slew of flavors and ingredients all over the world. But in the 19th century, it started being served between two slices of bread on ships transporting immigrants to the US. In the 21st century, the burger is a major sensation in Brussels where restaurants don’t hesitate to add it to their menu. Some have even devoted their entire establishment to this special patty.
