Coming from the land of Myron Mixon and other BBQ legends of the South, I've tried a lot of Barbeque sauces. I usually make my own. But on a whim one day because I needed some bulk sauce, more than was practical for me to make because I was in a hurry, I went to Save a Lot and bought their store brand "Kurt's". By far the best BBQ "bought" sauce I have tried. I was blown away. Sweet/tangy flavor with just a hint of cumin.
Tiger Sauce is a really good all around hot sauce for a little heat and a little sweet and a good add in for cheap bbq sauce. My wife uses it on baked flounder along with a little melted butter.
But for "hot pepper/vinegar" sauce, Crystal or Louisiana hot sauce is better to me than Tobasco brand and a better value for sure.
