I have made this sauce too and completely agree. Only thing I do differently is add 1/2 tsp cayenne to give it some heat. Aaron suggests this sauce for his brisket and dinos.
Here's the recipe copied from the internet:
- 1 14-ounce bottle of ketchup (I buy ketchup in bulk so I use about 2 cups)
- ½ cup plus 2 Tbsp water
- ¼ cup plus 1 Tbsp cider vinegar
- ¼ cup plus 1 Tbsp white vinegar
- ¼ cup plus 1½ tsp brown sugar
- 2 Tbsp plus 1½ tsp Worcestershire sauce
- 1 Tbsp chile powder
- 1 Tbsp ground cumin
- 1½ tsp kosher salt
- 1½ tsp coarse black pepper
Combine all ingredients in a saucepan and bring to a simmer. Reduce to low and let it go for 10 minutes then remove from heat and let it cool
