Greetings, all- The old-fashioned home-made hot pepper seasoning that my great- aunts [and the rest of the family] always referred to as 'Pepper-Sauce' was made by simply placing whatever hot peppers were available in a bottle and cov- ering them with vinegar. When the bottle was about half empty of liquid more vinegar was added. One aunt kept this in a cut-glass bottle with a glass stopper but we more plebian branches of the family used whatever was available, often used ketchup bottles...the metal caps eventually rusted & had to be replaced! The vinegar was never heated. Pure vinegar is sufficiently acid that this never spoils, but it darkens [oxidation?] over the months like opened unrefrigerated Tabasco sauce. This doesn't affect the flavor, IMHO. My guess is that if these were heat processed just long enough to vacuum- seal the containers the darkening would be retarded; refrigeration would probab ly help slow down the darkening also. We make several bottles of this every fall; they make colorful small gifts, especially for those Southerners who believe that such concoctions are indespen sible to the proper enjoyment of mustard, collard, & turnip greens as well as blackeyed & crowder peas. Rael, does this make you hungry? Gator Slide Farm Micanopy, FL
