What makes a hot dog authentically Chicago-style?
The signature elements are a poppy seed bun, yellow mustard, bright green relish, chopped onions, tomato wedges, a dill pickle spear, sport peppers, and celery salt—never ketchup.
Can I use regular hot dog buns instead of poppy seed?
You can, but poppy seed buns are traditional and contribute to the authentic flavor. Ensure buns are steamed to stay soft.
Where do I find sport peppers?
Sport peppers are available at specialty grocers, Latin markets, and online retailers. Fresh Thai chilies or jalapeños are spicy alternatives, though less traditional.
How do I score the franks?
Using a sharp knife, make shallow diagonal cuts across the surface of each frank before grilling to help it cook evenly and improve texture.
Can this recipe be made ahead?
Grill and assemble franks fresh for best results. Prepare toppings (chop onions, cut tomatoes, slice pickles) up to 4 hours ahead and store refrigerated.
