Coney dogs with Coney Island meat sauce

Put the diced onion, ground beef, minced garlic and butter into a saucepan.

Add celery salt, chili powder, black pepper, salt, ground cumin and cayenne. Do not brown the meat.

Add water and ketchup.

Bring up to a simmer over medium-high heat, mixing and mashing continuously with a potato masher until the meat breaks into the smallest possible particles and the mixture is smooth.

Lower the heat to medium-low and simmer, stirring occasionally, until it reduces and thickens; do not skim the fat.

Taste for seasoning, adding salt and checking for heat.

Warm a bun in the oven, add a boiled hot dog, spoon over the meat sauce, drizzle with yellow mustard and top with diced raw onions.
