luca, i wish i could fly you to nyc, the world capitol of hot dogs, for a real treat. (chicago is a close secind)
we have every way of preparing the dog itself: boil, broiled, grilled, griddled, pan fried, deep fried, baked, and even cooked on a stick over a campfire.
much like pizza, there are standard toppings, and then crazy toppings. all over america you'll find new or different things to add to the humble dog to make it special to that region, shop, or even house. again, it's just like italy in it's a common ly cooked food, but everyone has their favourite way, their standard way, and the way they get their freak on.
