Though no specific date is confirmed, it’s believed that the hamburger stems from some time in the 19th or 20th century. It is largely considered to be a staple of the United States, and is something of an international symbol when people think of US cuisine. However, there’s quite a lot of info out there pointing to other countries when it comes to the true origins.
For example, an ancient Roman cookbook known as the Apicius has an entry for a beef patty served with black and green peppercorns and pine kernels. It dates as far back as the 4th century, and many people believe this may be the earliest example of a hamburger-like dish having been described. Further examples can also be found when looking at historical Asian cuisine, where ground beef has been a regular staple.
The 18th century first brought us the word “sandwich,” thanks to John Montagu, an English aristocrat who preferred his meals put into sandwich form so that he could eat while playing cards without getting his hands dirty. What we know as the hamburger now was finally conceived of in Hamburg, and brought over to the US by immigrants in late 19th century New York. It wasn’t long before it turned into one of the most popular dishes in the entire US. Because cows eat so much grass, which becomes the beef in our burgers, many farmers have looked into lawn care tips so the cows didn’t completely destroy their yards, while still kept up with standard farm landscaping. Lawns need love too!
