575. GAS-COOKING can scarcely now be considered a novelty,—many establishments, both small and large, have been fitted with apparatus for cooking by this mode, which undoubtedly exhibits some advantages. Thus the heat may be more regularly supplied to the substance cooking, and the operation is essentially a clean one, because there can be no cinders or other dirt to be provided for. Some labour and attention necessary, too, with a coal fire or close stove, may be saved; and, besides this, it may, perhaps, be said that culinary operations are reduced, by this means, to something like a certainty.
576. THERE ARE, HOWEVER, WE THINK, MANY OBJECTIONS to this mode of cooking, more especially when applied to small domestic establishments. For instance, the ingenious machinery necessary for carrying it out, requires cooks perfectly conversant with its use; and if the gas, when the cooking operations are finished, be not turned off, there will be a large increase in the cost of cooking, instead of the economy which it has been supposed to bring. For large establishments, such as some of the immense London warehouses, where a large number of young men have to be catered for daily, it may be well adapted, as it is just possible that a slight increase in the supply of gas necessary for a couple of joints, may serve equally to cook a dozen dishes.
ROASTING.
577. OF THE VARIOUS METHODS OF PREPARING MEAT, ROASTING is that which most effectually preserves its nutritive qualities. Meat is roasted by being exposed to the direct influence of the fire. This is done by placing the meat before an open grate, and keeping it in motion to prevent the scorching on any particular part. When meat is properly roasted, the outer layer of its albumen is coagulated, and thus presents a barrier to the exit of the juice. In roasting meat, the heat must be strongest at first, and it should then be much reduced. To have a good juicy roast, therefore, the fire must be red and vigorous at the very commencement of the operation. In the most careful roasting, some of the juice is squeezed out of the meat: this evaporates on the surface of the meat, and gives it a dark brown colour, a rich lustre, and a strong aromatic taste. Besides these effects on the albumen and the expelled juice, roasting converts the cellular tissue of the meat into gelatine, and melts the fat out of the fat-cells.
578. IF A SPIT is used to support the meat before the fire, it should be kept quite bright. Sand and water ought to be used to scour it with, for brickdust and oil may give a disagreeable taste to the meat. When well scoured, it must be wiped quite dry with a clean cloth; and, in spitting the meat, the prime parts should be left untouched, so as to avoid any great escape of its juices.
579. KITCHENS IN LARGE ESTABLISHMENTS are usually fitted with what are termed "smoke-jacks." By means of these, several spits, if required, may be turned at the same time. This not being, of course, necessary in smaller establishments, a roasting apparatus, more economical in its consumption of coal, is more frequently in use.
[Illustration: BOTTLE-JACK, WITH WHEEL AND HOOK.]
580. THE BOTTLE-JACK, of which we here give an illustration, with the wheel and hook, and showing the precise manner of using it, is now commonly used in many kitchens. This consists of a spring inclosed in a brass cylinder, and requires winding up before it is used, and sometimes, also, during the operation of roasting. The joint is fixed to an iron hook, which is suspended by a chain connected with a wheel, and which, in its turn, is connected with the bottle-jack. Beneath it stands the dripping-pan, which we have also engraved, together with the basting-ladle, the use of which latter should not be spared; as there can be no good roast without good basting. "Spare the rod, and spoil the child," might easily be paraphrased into "Spare the basting, and spoil the meat." If the joint is small and light, and so turns unsteadily, this may be remedied by fixing to the wheel one of the kitchen weights. Sometimes this jack is fixed inside a screen; but there is this objection to this apparatus,—that the meat cooked in it resembles the flavour of baked meat. This is derived from its being so completely surrounded with the tin, that no sufficient current of air gets to it. It will be found preferable to make use of a common meat-screen, such as is shown in the woodcut. This contains shelves for warming plates and dishes; and with this, the reflection not being so powerful, and more air being admitted to the joint, the roast may be very excellently cooked.
