Although many people might think so, the famous slider is not just a small hamburger, but a very specific food item. First of all, a small ball of ground meat is smashed on a well-oiled griddle until very thin, accompanied by onions, which fry into the meat during the cooking process.

The meat is then flipped, and other ingredients are added on top of the meat, including the slider bun which absorbs the aromas and flavors while it steams. Originally, slider was a term describing small burgers at White Castle restaurants throughout the United States of America.

There are several theories as to why they’re called sliders: one says that they slide down easily because people typically eat more than just one, another says it’s because they slide across the griddle to make room for new meat patties, while White Castle says it’s because they slide out of their boxes with ease.
