The hot dog is topped with yellow mustard, chopped white onions, bright green sweet pickle relish, a dill pickle spear, tomato slices or wedges, pickled sport peppers and a dash of celery salt . The complete assembly of a Chicago hot dog is said to be "dragged through the garden" due to the many toppings . The method for cooking the hot dog itself varies depending on the vendor's preference . Most often they are steamed, water - simmered, or less often grilled over charcoal (in which case they are referred to as "char - dogs"). </P> <P> The canonical recipe does not include ketchup, and there is a widely shared, strong opinion among many Chicagoans and aficionados that ketchup is unacceptable . A number of Chicago hot dog vendors do not offer ketchup as a condiment . For National Hot Dog Day on July 19, 2017, Heinz created controversy by introducing ketchup, labeled as "Chicago Dog Sauce", to the disdain of many Chicagoans--but their effort also unearthed a minority of ketchup aficionados in the city . </P>
