This may be slightly askew of the topic but to my way of thinking the best way to avoid strange chemicals in hot sauce is to make your own pepper mash. A quart of pepper mash will go a long long way and once you have the base (pepper mash) you can create any sort of hot sauce that might please you. (not counting extracts) I've just started to dip into the second quart of pepper mash I created from peppers I snarfed at the last Open Fields I attended. It was a beautiful mix of many different and tasty peppers and I wouldn't give up this quart of mash for love or money. Jose
