Ingredients
- 2 medium onions, finely chopped
- 1 green (or red) bell pepper, finely chopped
- 6 tablespoons unsalted butter
- 2 tablespoons granulated sugar
- 1 teaspoon dry mustard (I like Colemans)

- 1/4 – 1/2 teaspoon red pepper flakes (or 1 teaspoon chili crisp)
- 1 teaspoon Worcestershire sauce
Instructions
- In a large saucepan, melt the butter over medium heat.
- Add the diced onions and bell pepper. Sauté until very soft and fragrant, about 10-12 minutes.
- Stir in the sugar, dry mustard, salt and red pepper flakes (or chili crisp). Cook for 1-2 minutes to give the spices a chance to bloom.
- Add the ketchup, cider vinegar, and Worcestershire sauce. Stir well to combine.
- Simmer uncovered for 15-20 minutes, stirring occasionally until the sauce is thickened and glossy.
- Serve warm over hot dogs, burgers or grilled sausage.
