>>21398405>All beef dogs. Onions sauce, krauts,This. Most carts even state the brand of hot dogs, from Sabretts to Nathans. They're going to be all beef. The tomato-y sweet onions will be sabrets, which you can buy in the jar at the grocery or some other almost chutney kind of new england style piccalilli like Howards, which is some version of red bell peppers relish. This may have a hint of pickling spice and mustard seeds, tumeric and lots of onions, and well sugar.
I actually like the snap of a traditional sausage, and one that was grilled not steamed/boiled, but a cart is about the toppings. The "dirty water" is simply what happens with protein in the water.
