Frying is a process somewhat intermediate between roasting and boiling. Indeed, in one sense, it may be termed boiling, as it is the application of heat to the substance to be cooked, through the medium of melted fat, raised to the boiling temperature. The effect on the meat is very peculiar, and easily distinguished from every other mode of cooking. The meat is prepared in the same way as in broiling, by cutting it into chops, or slices, of not more than half an inch or three quarters in thickness. A sufficient quantity of mutton or beef suet, butter, lard, or oil, being melted in a pan, and made boiling-hot, the meat is laid in it. It is not necessary that the meat be _wholly_ immersed in the boiling fat; if it be immersed in part, it will be quite sufficient. When flesh is the substance to be fried, the pieces, previously to their being put into the pan, are sometimes brushed over with eggs and crumbs of stale bread, flour, or any other farinaceous substance. This application may also be made when the meat is nearly cooked. The intention of it is to cover the meat with a thin brown crust, the savour of which increases the relish of the dish. Fish are, for the most part, treated in this manner when fried. It answers well with trout, whitings, flounders, and soles. When this application is made to the meat previously to its being put into the pan, the peculiar flavour of the meat is more effectually retained. One of the best preparations for this purpose is oatmeal, flour, or crumbs of stale bread, made into a liquid paste with the yolk and white of eggs. Vegetable, as well as animal substances, are subjected to this process, though it is always at the expense of their wholesome and nutritive qualities; and not always to the improvement of their taste and flavour. As in the case of animal substances, all the juices are, by frying, extracted from the vegetables; with this difference, however, that their place is not supplied by the melted fat; for the starch of the vegetables (potatoes for example) is rendered insoluble in water by the fat, and exhibits a corneous appearance and texture. Fried potatoes are the most familiar instance of the process. When cut into thin slices and fried in oil, butter, or lard, they are rendered semi-transparent. Cabbage, or the stalks, leaves, and fruits of other vegetable substances, previously boiled and then fried, shrink, and become more easy to break, in proportion as the water is driven off from them, as this, during their previous boiling, dissolves the saccharine and amylaceous matter which rendered them supple and juicy. These principles are much better prepared and improved by boiling; they are very much deteriorated by the boiling fat in the frying pan.
