62. Vinegar.—Vinegar is an acid liquid, obtained in this country by allowing a kind of weak beer to become sour.
It has the power of preventing substances putrefying, and is used for this purpose in making pickles. If taken with our food in small quantity it helps us to digest many substances that are difficult of digestion; in large quantity it is very injurious. It is employed in cookery to assist in softening the fibres of tough meat,¹ and to pickle fish, vegetables, &c.
