I don't know about other areas, but "gourmet" hot sauces have become quite the cottage industry around here. I wouldn't even hazard a guess as to how many people there are making sauces and selling them through gourmet grocers, Cajun restaurants, flea markets and craft fairs. All ya need is a garden patch full of pepper plants, the willingness to come up with a recipe that tastes better than the three-for-a-dollar stuff at WalMart, and, most importantly, a catchy name and distinctive label to make your products stand out from those of all the other folks who are doing the same thing.
