There are two ways of frying employed by the French cook. One is, to immerse the article to be cooked in _boiling_ fat, with an emphasis on the present participle,—and the philosophical principle is, so immediately to crisp every pore, at the first moment or two of immersion, as effectually to seal the interior against the intrusion of greasy particles; it can then remain as long as may be necessary thoroughly to cook it, without imbibing any more of the boiling fluid than if it were inclosed in an egg-shell. The other method is to rub a perfectly smooth iron surface with just enough of some oily substance to prevent the meat from adhering, and cook it with a quick heat, as cakes are baked on a griddle. In both these cases there must be the most rapid application of heat that can be made without burning, and by the adroitness shown in working out this problem the skill of the cook is tested. Any one whose cook attains this important secret will find fried things quite as digestible and often more palatable than any other. In the second department of meat-cookery, to wit, the slow and gradual application of heat for the softening and dissolution of its fibre and the extraction of its juices, common cooks are equally untrained. Where is the so-called cook who understands how to prepare soups and stews? These are precisely the articles in which a French kitchen excels. The soup-kettle, made with a double bottom, to prevent burning, is a permanent, ever-present institution, and the coarsest and most impracticable meats distilled through that alembic come out again in soups, jellies, or savory stews. The toughest cartilage, even the bones, being first cracked, are here made to give forth their hidden virtues, and to rise in delicate and appetizing forms. One great law governs all these preparations: the application of heat must be gradual, steady, long protracted, never reaching the point of active boiling. Hours of quiet simmering dissolve all dissoluble parts, soften the sternest fibre, and unlock every minute cell in which Nature has stored away her treasures of nourishment. This careful and protracted application of heat and the skilful use of flavors constitute the two main points in all those nice preparations of meat for which the French have so many names,—processes by which a delicacy can be imparted to the coarsest and cheapest food superior to that of the finest articles under less philosophic treatment. French soups and stews are a study,—and they would not be an unprofitable one to any person who wishes to live with comfort and even elegance on small means.
