Coney Island Hot Dogs - cooking recipe

Ingredients

1 1/2 pounds lean ground beef
2 cups water, or more to taste
1/2 cup diced onion
1/3 cup ketchup
2 tablespoons butter
2 cloves garlic, crushed
2 tablespoons chili powder, or more to taste
1 1/2 teaspoons salt, or to taste
1 teaspoon freshly ground black pepper, or to taste
1 teaspoon ground cumin, or to taste
1/2 teaspoon celery salt, or to taste
1 pinch cayenne pepper, or to taste
8 all-beef hot dogs
8 hot dog buns
1/4 cup prepared yellow mustard, or to taste
1/4 cup diced onion, or to taste

Preparation

Combine ground beef, water, 1/2 cup diced onion, ketchup, butter, garlic, chili powder, salt, black pepper, cumin, celery salt, and cayenne pepper together in a pot. Mix with a potato masher or spatula over medium-high heat until mixture has a finely ground consistency and begins to bubble, about 10 minutes.
Bring beef mixture to a simmer, reduce heat to medium-low, and cook, stirring occasionally, until sauce thickens and reduces, about 1 hour. Season with salt and pepper to taste.
Bring a large pot of water to a boil. Cook hot dogs in boiling water until heated through, 5 to 7 minutes.
Preheat oven to 350 degrees F (175 degrees C). Arrange hot dog buns on a baking sheet.
Cook buns in the preheated oven until soft and warm, 2 to 3 minutes.
Place 1 bun on a plate. Place a hot dog in the bun and top with meat sauce. Drizzle yellow mustard and diced onion over the meat sauce. Repeat with remaining hot dogs.
