New York Street Cart Hot Dog

The 'dirty water dog' nickname comes from the pot of seasoned water franks simmer in all day on the cart — not from being unhygienic.

An all-beef frank is kept warm in simmering water inside a stainless-steel cart, then tucked into a steamed bun and topped with spicy brown mustard, sauerkraut, and sweet stewed onions. Vendors have sold hot dogs this way from licensed street carts on Manhattan corners since the 1800s, with the most coveted spots near parks and office towers fiercely contested among vendors.

Why it's made this way: The cart format survives because it was built to feed people who couldn't stop for a sit-down meal — dockworkers and factory hands originally, office workers and tourists today — and a pot of hot water lets a vendor hold franks ready to serve for hours without a kitchen.
