Chicago Hot Dogs, the Recipe, and the NK-17 Rating

As hot dog season winds down this Labor Day Weekend, it's as good a time as any to check in on the Chicago hot dog.

Chicagoans know that the true Chicago style hot dog does not make room for ketchup. But, did you also know that there is an NK-17 rule? That is, according to Vienna Beef, the no ketchup rule really kicks in when you turn 17?

This is how Chicagoans divert their kids to the mustard over time and thus protect the tradition over the long haul. That's my theory at least. In case you were wondering.
