Steve, I made your No. 5 sauce this weekend with pulled pork. This was just the sauce that I was looking for, tomato based with a little vinegar, not overwhelming vinegar like some other sauces.
Also, in addition to your ingrediants, I added about a teaspoon of beef paste and about 1/2 cup of water. Since I didn't have pan drippings I thought that beef paste would be a good substitute and it gives the sauce some richness. Thanks for the sauce.
