I heard this morning that Heinz started selling "Chicago Dog Sauce" as a way to get around the Chicago tradition of no ketchup on hot dogs (and at $5 plus $2 shipping for a 14 oz bottle, it is an overpriced novelty).
But it got me thinking why are so many people vehemently opposed to putting ketchup on hot dogs. Some say it is because ketchup is too sweet. But there doesn't seem to be an objection to putting even sweeter relish on hot dogs. Plus sweet and salty are complementary flavors, which is one of the reasons prosciutto pairs well with sweet melon. Others say that ketchup overpowers the flavor of the hot dog. But mustard is a much strong flavor. And I'm not sure how someone in Chicago can be concerned about ketchup having an overpowering flavor, when they are topping a dog with yellow mustard, sweet relish, chopped onion, tomato slices, a pepper, and celery salt.
So what is the real objection to ketchup?
