Ingredients
- ½ cup water
- 1 tsp cornstarch or arrowroot
- 1 Tbsp tomato paste (or substitute ketchup)
- 1 tsp balsamic vinegar
- 1 tsp dijon-style mustard
- 1 tsp brown sugar
- ¼ tsp hot sauce
- 1 Tbsp olive oil
- 2 sweet onions, sliced thin
- ½ tsp kosher salt
- 2 garlic cloves, minced
Instructions
- Combine the water and cornstarch in a bowl and whisk until there are no lumps.
- Whisk in the tomato paste, balsamic vinegar, mustard, brown sugar, and hot sauce.
- Warm the oil in a large skillet, not a non-stick, over medium-high heat. Add the onions and sprinkle with the salt. This helps pull the moisture out. Stir onions around occasionally with a wooden spoon so they don't burn. Cook until the edges start to brown. Whatever you do, do not let them burn. Add the garlic and cook for another minute.
- Add the liquid mixture, stir, and rub the pan with the wooden spoon to scrape up all the flavorful fond (the brown bits on the bottom).
- Turn the stove to low and simmer with the lid on for 1 hour. Check frequently to make sure it is not burning and the water has not evaporated. Add water if needed. The final result should be thick – not runny, but not pasty. Taste and adjust salt and other flavors as you wish.
- Serve on hot dogs, sausages, or hamburgers.
