Born in the Bronx, raised in Queens. My father worked for Pan Am in the day (data Control), drove a New York Cab at night, and on the weekends he owned a New York Hot Dog Cart. Before he passed away in February of 2004, he did give me the recipe to the Onion Sauce. When everybody else is saying to use pasta sauce, and this and that, the truth is there are only six ingredients. Bobby Flay is about the only one who got it close. In New York a true New York Hot Dog ordered from a cart is, Nathan Hot Dogs, Mustard, Onion Sauce, and topped with Sauerkraut. I wanted to write this recipe for a long time but after seeing so many Onion Sauce recipes, and hearing how so many people are from New York, it is time to post the original recipe.
