No. 45 To Make Good and Cheap Vinegar
Take three quarts of molasses, add to it eight gallons of rain water; turn the mixture into a clean cask, shake it well two or three times, throw in a few spoonfuls of good yeast, or two yeast cakes; place the cask in a warm place, and in ten days throw in it a sheet of common brown paper, smeared with molasses; it should be torn into narrow strips. This paper seems necessary to form mother, in making vinegar, unless you use whisky to commence the fermentation; then paper is not necessary.
