Grace hot sauce--made in Jamaice, sold in Bermuda and available in Canada--just a few drops does the trick for me. A little hotter than Tabasco. I use it in soups, baked beans, pasta sauces, you name it. I think it's true about hot peppers not causing ulcers, my experience is that salt is worse for that. Here up North the Acadiens use a lot of salt, goes back to the days of no refrigeration I suspect

Voodoo Queen Habenero sauce. Not too hot, full flavored. Good on everything.
