I created this sauce through my many years of commercial cooking. I found that my family really enjoyed it when we had family reunions and I would either make BBQ Beef or BBQ pork slices with it. My Father-in-law loved it so much he would put it on anything he ate. I would prepare a gallon of it and ship it to him in California.
In a Dutch oven over medium heat, saute pepper and onion in oil until tender. Turn heat down to low. Add tomato paste and cook for about 2 minutes; add tomato sauce and ketchup and rest of ingredients. Mix well, then bring mixture to a boil and allow to boil for about 4 minutes, stirring so that sauce doesn’t stick to bottom of pan.
Reduce heat and allow to simmer for about 2 hours, stirring occassionally, until sauce thickens and reduces.
For best results, prepare sauce one day ahead of serving. Bottle or freeze extra sauce. It will last up to 1 year in the freezer, 6 months in the refrigerator.
Note: For an even thicker sauce, mix 1 cup of water with ¼ cup of cornstarch and stir into sauce. Bring mixture back to boil until sauce thickens to desired consistency, then reduce heat and simmer until done.
