Why is the hamburger called a hamburger?

The hamburger takes its name from the German city of Hamburg, where it was customary to serve a hamburger steak, which became known as a hamburger steak. German immigrants brought this dish to the United States. Over time, the hamburger steak was served between two slices of bread and became known as a "hamburger."

Since when has the hamburger existed?

The hamburger was probably invented in the mid-19th century. Over the course of the 20th century, it became a symbol of American fast-food culture.

Incidentally, the hamburger became popular in Germany in the late 1970s, when international fast-food chains like McDonald's and Burger King opened their stores there. Since then, the popularity of hamburgers has steadily increased. Today, there are numerous fast-food restaurants and gourmet burger shops throughout the country.

From veggie to vegan, since when have the new burger variations been available?

Veggie and vegan burgers have been around for several decades, but they have become more popular in recent years due to increasing awareness of health and environmental concerns. The first vegan burger was likely introduced in the 1980s, but the exact time may vary depending on how one defines a "vegan burger." In recent years, companies like Beyond Meat and Impossible Foods have developed vegan burgers that are very similar to meat in taste and texture. These products have only been on the market since the 2010s.
