Ingredients:
- 1 lb lean ground beef
- 1 small onion, finely diced
- 1 stalk celery, finely diced
- 15 oz tomato sauce
- 2 tbsp brown sugar
- 1 tbsp yellow mustard
- 1 tbsp chili powder
- 1 tsp Worcestershire sauce
- 1/2 tsp salt
- 1/4 tsp black pepper
Instructions:
- Heat a large skillet or heavy bottomed saucepan over medium high heat. Add the ground beef, diced onion, and celery.
- Stir frequently, breaking the meat into very small crumbles until the beef is deep brown and the onions are translucent. Note: Don't rush the browning; this is where the flavor lives.
- Lower the heat to medium low.
- Stir in the tomato sauce, brown sugar, mustard, chili powder, and Worcestershire sauce.
- Bring the mixture to a gentle bubble, then reduce heat to low.
- Simmer uncovered for 30 minutes, stirring occasionally until the sauce has thickened and turned a rich mahogany color. Note: Use a technique similar to what [Serious Eats](https://seriouseats.com) suggests for reducing sauces to concentrate flavor.
- Remove the pan from the heat.
- Give the sauce one final vigorous stir to ensure the sugar is fully dissolved.
- Let it rest for 5 minutes before serving.
