A slider is a very small hamburger, meant for frenzied consumption in multiple quantities. You don’t order one, or even three — you order ten and devour all of them in less than three minutes, preferably while you’re still in your car at the franchise’s parking lot. In the summer of 1987, Burger King introduced their own sliders, Burger Bundles, and they did a booming business, particularly among teenagers and late night customers.
Despite the Burger Bundles’ popularity, preparing them was more difficult than anyone realized. Line cooks experienced “operational difficulties” when working with the tiny patties, and the undersized burgers frequently fell through the grating of the kitchen’s broilers. Ultimately, the technical demands required to make them proved too much, and they were discontinued just months after they were introduced.
