Hot Dog

German Frankfurter and Wiener sausages came to the U.S. with mid-1800s immigration. The bun-and-sausage combination crystallized at American baseball parks and street carts in the 1890s — Coney Island vendor Charles Feltman sold them from 1867; Nathan Handwerker (his ex-employee) undercut him in 1916, founding Nathan's Famous. The 'hot dog' name is often credited to a 1900 cartoon by T.A. Dorgan, but historians have debunked this: the cartoon was never found, Dorgan's earliest documented use is 1906, and 'hot dog' was already widespread by the 1890s (attested 1884). It most likely evolved from the earlier slang 'dachshund sausage,' a joke on Germans' long, thin dogs.

1860s German immigrants brought frankfurters; Coney Island Charles Feltman sold them in milk rolls in 1867; Nathan Handwerker undercut him at 5¢ in 1916. New York street carts run «dirty water dogs» — boiled, not grilled.

A cured-and-smoked sausage in a soft, top-split or side-split bun. The sausage should snap when bitten — natural casing under tension. Toppings are city-coded: New York is mustard and onion sauce; Chicago is mustard, relish, onion, tomato, sport pepper, celery salt, pickle spear, no ketchup ever; Sonoran is bacon-wrapped with beans and salsa. The bun is steamed or griddled, never crusty.

The 'snap' is mechanical: natural sheep or hog casing dries slightly during smoking, tightens around the emulsion, and resists the bite until it ruptures with audible give. Skinless dogs (extruded into cellulose then peeled) cannot snap; they have a uniform soft mouthfeel. Steaming the bun before plating keeps it pliable enough to fold without cracking around the sausage.
