New York's iconic hot dogs are a big part of the Big Apple's food culture, and the reason they're so irresistible is because of their toppings, buns, and "dirty water."
The "dirty water" may look murky, but it's loaded up with a delicious combination of spices like cumin, nutmeg, and red pepper that give it a very interesting color.
Some stands even include ingredients like vinegar, tomato sauce, sauerkraut, and onions. The flavor left behind by the preceding batch of hot dogs also adds to the unique taste.
