Sugar Vinegar.
To every gallon of water, put two pounds of the very coarsest sugar: boil and skim thoroughly; then put one quart of cold water for every gallon of hot. When cool, put into it a toast spread with yeast. Stir it nine days; then barrel, and set it in a place where the sun will lie on it, with a bit of slate on the bunghole.
When sufficiently sour, it may be bottled: or may be used from the cask, with a wooden spigot and faucet.
