[Hamburger]

Do you ever have an uncontrollable craving for hamburgers? I personally like hamburgers because it takes me back to my childhood when I open my big mouth and eat them enthusiastically. Hamburgers are America's national dish. Family, lunch break at work, beer in hand, elderly couple. It was obvious that hamburgers are loved by many people at all the hamburger stores.

I was somewhat thinking that hamburgers were born in the U.S., as there are several hamburger chains that originated in the U.S. in Japan, but in fact, their roots can be traced back to the Tatars, a nomadic people who lived from northern Asia to eastern Europe around the 13th century. The Tatars devised a way to make stringy horse meat easier to eat, and the minced meat dish known as tartar steak was born. This dish was introduced to Europe and became the "hamburger steak" in Hamburg, Germany. It was introduced to the U.S. by German immigrants. There are various theories about the origin of the hamburger in its present form, which is a hamburger sandwiched between bread, but there is a record that the hamburger in its present form was sold at the St. Louis World's Fair in 1904.

There are several hamburger chains in the U.S., and each chain is unique in its own way, such as their insistence on not using any frozen ingredients, the ability to customize toppings to your own taste, and the existence of back-of-the-envelope menus. Whether you want a single or double patty, grilled or raw onions, the possibilities are endless, and you can't help but think about it. And let's not forget the sides. Fries also vary in shape and flavor, depending on the restaurant. In most cases, additional condiments such as ketchup and salt are self-service and can be added as much as you like. Some restaurants focus on drinks and shakes. I was surprised at the variety of hamburgers and the attention to detail that the people of the home country put into their hamburgers.

The hamburger crossed the sea from the Eurasian continent to its current form in the U.S. It also spread across borders to the rest of the world, gradually transforming itself into a form loved by the local people in each region. It was an experience that I could not help but feel the depth and fascination of food.
