Slider Fact Blast

The original slider is most commonly associated with White Castle, which is often credited as the first fast food burger chain in the country. White Castle coined the efficient cooking method of poking five small holes in the square-shaped beef patty to help it cook quickly by eliminating the need to flip the burger. Established in Wichita, Kansas in 1921, the first White Castle location sold sliders for just five cents each. At less than three inches across, however, people typically eat more than one at a time, negating the cheapness of the burger. [Power Hour]
