Leave it to Heinz to pull the ultimate prank on Chicago hot dog eaters.
There are few foodie things Chicagoans will passionately defend when it comes to city eating: deep dish pizza is in fact pizza and you don't put ketchup on your hot dogs.
For Heinz, that rule was clearly a slap in the face. So, in an effort to get city residents to "reconsider their anti-ketchup stance, the popular ketcup-maker did the unthinkable.
As part of National Hot Dog Day, the company unveiled its new "Chicago Dog Sauce," described as "a delicious sauce made with red ripe tomatoes and a special blend of spices and flavorings, to complement to your Chicago-Style dog."
The company brought the new sauce to the hands of several Chicagoans, asking them to try the red-colored topping on their hot dogs.
And many did.
But it wasn't until after they ate the hot dog that Heinz revealed its new "Chicago Dog Sauce" was actually just ketchup.
The new sauce will be available for a limited time for $5 plus shipping at chicagodogsauce.com.
