Coney dog
A Coney Island hot dog, Coney dog, or Coney is a hot dog in a bun topped with a savory meat sauce and sometimes other toppings. It is often offered as part of a menu of classic American diner dishes and often at Coney Island restaurants. It is largely a phenomenon related to immigration from Greece and the region of Macedonia to the United States in the early 20th century. "Virtually all": 233 Coney Island variations were developed, apparently independently, by immigrants in the early 1900s, many fleeing the Balkan Wars, who entered the US through Ellis Island in New York City. Family stories of the development of the dishes often included anecdotes about visits to Coney Island. The origin of the style is somewhat murky: there were parallel developments in New York, Michigan, Ohio, and elsewhere around the United States. The first documented European name for the island is the Dutch name Conyne Eylandt or Conynge Eylandt. This would roughly be equivalent to Konijn Eiland using modern Dutch spelling, meaning Rabbit Island. The name was anglicized to Coney Island after the English took over the colony in 1664, coney being the corresponding English word. The hot dog's fame later spread from this part of Brooklyn, New York, where Nathan Handwerker, a Polish Jewish immigrant was an early entrepreneur who sold them at his stand in Coney Island. His business was later named "Nathan's," an iconic brand that remains popular as both a fast-food chain and as a grocery product. The alternate name for a hot dog—a "Coney," most likely derived from the positive regional and national publicity Nathan's began to generate.
