Coney Island Hot Dogs

Ingredients

• 1 1/2 lbs lean ground beef
• 2 cups water, or as needed
• 3/4 cup diced onion, divided
• 1/3 cup ketchup
• 2 tbsp butter
• 2 cloves garlic, crushed
• 2 tbsp chili powder, or more to taste
• 1 1/2 tsp salt, or to taste
• 1 tsp freshly ground black pepper, or to taste
• 1 tsp ground cumin, or to taste
• 1/2 tsp 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

Instructions

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