I have a pickle recipe that calls for using grape leaves. Is it safe or necessary?
Some old fashioned pickle recipes call for adding a grape leaf to each jar of pickles to make them crisper. Grape leaves contain a substance which inhibits the enzymes that make pickles soft. It is safe, but is not necessary if good quality ingredients and up-to-date procedures are used.
