564. THE TIME ALLOWED FOR THE OPERATION OF BOILING must be regulated according to the size and quality of the meat. As a general rule, twenty minutes, reckoning from the moment when the boiling commences, may be allowed for every pound of meat. All the best authorities, however, agree in this, that the longer the boiling the more perfect the operation.
565. A FEW OBSERVATIONS ON THE NUTRITIVE VALUE OF SALTED MEAT may be properly introduced in this place. Every housewife knows that dry salt in contact with fresh meat gradually becomes fluid brine. The application of salt causes the fibres of the meat to contract, and the juice to flow out from its pores: as much as one-third of the juice of the meat is often forced out in this manner. Now, as this juice is pure extract of meat, containing albumen, osmazome, and other valuable principles, it follows that meat which has been preserved by the action of salt can never have the nutritive properties of fresh meat.
566. THE VESSELS USED FOR BOILING should be made of cast-iron, well tinned within, and provided with closely-fitting lids. They must be kept scrupulously clean, otherwise they will render the meat cooked in them unsightly and unwholesome. Copper pans, if used at all, should be reserved for operations that are performed with rapidity; as, by long contact with copper, food may become dangerously contaminated. The kettle in which a joint is dressed should be large enough to allow room for a good supply of water; if the meat be cramped and be surrounded with but little water, it will be stewed, not boiled.
567. IN STEWING, IT IS NOT REQUISITE to have so great a heat as in boiling. A gentle simmering in a small quantity of water, so that the meat is stewed almost in its own juices, is all that is necessary. It is a method much used on the continent, and is wholesome and economical.

Two useful culinary vessels are represented above. One is a boiling-pot, in which large joints may be boiled; the other is a stewpan, with a closely-fitting lid, to which is attached a long handle; so that the cover can be removed without scalding the fingers.

568. THE HOT-PLATE is a modern improvement on the old kitchen ranges, being used for boiling and stewing. It is a plate of cast iron, having a closed fire burning beneath it, by which it is thoroughly well heated. On this plate are set the various saucepans, stewpans, &c.; and, by this convenient and economical method, a number of dishes may be prepared at one time. The culinary processes of braising and stewing are, in this manner, rendered more gradual, and consequently the substance acted on becomes more tender, and the gravy is not so much reduced.
