i had a very specific craving for a chicago style hot dog. so i went to some effort to get all the ingredients from memory, or at least as close as i could get in rural southwest wisconsin on short notice. no poppy seed buns and i had to substitute pepperoncini for pickled sport peppers, but hey, my mouth was watering as i assembled the glorious dogs and OH THE HUMANITY I FORGOT THE TOMATO SLICES!
sigh.
100% chicago style consists of all beef dog topped with yellow mustard, chopped white onions, sweet pickle relish, a dill pickle spear, tomato slices or wedges, pickled sport peppers and a bit of celery salt.
