Pickles.

The antiseptic power of vinegar is employed with advantage in domestic economy for preserving from decay a variety of fruits, roots, leaves, and other parts of vegetables, which by a species of refinement and luxury, are often considered as condiments to improve the relish of several kinds of food. Their qualities, no doubt, depends almost entirely on the vinegar, spice, or salt imbibed by them.

The art of preparing vinegar pickles consists in impregnating the vegetable substances with the strongest vinegar, to which are usually added a portion of common salt, and the most heating spices. To effect this object, the substance to be pickled is usually suffered to macerate, or slightly boiled with the acid, and afterwards kept infused in it, together with spices and salt.

It is customary to impregnate the article to be pickled first in a strong brine of common salt; but this is not absolutely necessary for the preservation of the pickled substance. To facilitate the action of the vinegar or salt, the articles to be pickled, especially such as walnuts, cucumbers, &c. should be punctured with a large needle or fork. To assist their preservation, and to improve their flavour, a variety of pungent and aromatic spices are added, which vary according to the fancy of the cook; pepper, pimento, cloves, mace, ginger, capsicum, and mustard, are the spices usually employed.

For the preparation of acid pickles, the vinegar prepared from wood, as in itself containing no substance liable to a spontaneous decay, is preferable to common malt vinegar, although the contrary has been asserted, because it is free from mucilage, which promotes the spoiling of common vinegar, and therefore the former is a better antiseptic than vinegar abounding in mucilage. We prepare our home-made pickles with this acid, and we are authorised to state that, although kept for years, they are inferior to none met with in commerce.

All pickles should be preserved in unglazed earthenware jars, carefully corked, and tied over with a bladder to exclude air. The vinegar used for preparing them should always be heated in an unglazed earthenware pan, it should never be suffered to boil, but poured over the substance to be pickled, just when it begins to simmer. The spices may be simmered with the vinegar.
