If you can't get to Chicago for this famous hot dog and you can't find all of the right ingredients, then fake it!!
I spent half my life living 90 miles north of Chicago. It was a place I loved to visit. I frequently hopped on the Amtrak train to go to Chicago and shop, to party and of course treat myself to its great restaurants. But my most favorite restaurant was a tiny greasy spoon place that served Chicago-Style hot dogs.
Now, because I live so far away that when I have a yearning for a Chicago-style hot dog, I can't even find poppy-seeded hot dog buns! So I fake with substitutes. And here's how.
What makes a real Chicago-Style hot dog?
Look for these ingredients:
Poppy seed buns
Bright green sweet pickle relish
Chopped white onions
Slice of dill pickle
Pickled sport pepper
A dash of celery salt
According to the Wikipedia on Chicago-style hot dog,
And for the record, ketchup is not to be applied!
I approach my "faux Chicago-style hot dog with close substitutions were necessary. For poppy seed bun, I bought regular buns, buttered the tops and sprinkled on poppy seeds. My initial search for sport peppers was unsuccessful, although I had later found that such places as Walmart may carry them. And they can probably be ordered online. A sport pepper is a pickled serrano pepper which add a tangy taste to the heat. Sport peppers are a must for an "authentic" Chicago-style pepper. I opted for a sliced banana peppers and that's why I call my Chicago-style pepper "faux"! In all other ingredients I was in luck.
As for the frankfurther, I confess that didn't steam it. I zapped it in the microwave. My next confession is that I ate a number of them over a course of three days. But I'm not telling how many. LOL.
To my Chicago readers, forgive me. But this is what one does when one lives a long way from the real thing!
