Add the rest of the ingredients, plus about half a cup of water. Stir well. 4) Simmer for 20-30 minutes. It will cook down a bit and flavors will combine. 5) Adjust the seasonings so you have the balance you want - you can add vinegar, artificial sweetener (liquid preferred), or hot sauce. (If it's too hot, adding more sweetener will tone it down.)
Note 2: If you can't find low carb catsup, leave it out, but add about a tablespoon of vinegar and some sweetener, to taste.
