From the beginning of the process to the end of it the boiling should be as gentle as possible. Causing any thing to boil violently in any culinary process, is very ill-judged; for it not only does not expedite, in the smallest degree, the process of cooking, but it occasions a most enormous waste of fuel, and by driving away with the steam many of the more volatile and more savoury particles of the ingredients, renders the victuals less good and less palatable: it is not by the bubbling up, or _violent boiling_, as it is called, of the water that culinary operations are expedited. One of the most essential conditions to be attended to in the boiling of meat is, to skim the pot well, and keep it really boiling, the slower the better. If the skimming be neglected, the coagulated albuminous matter will attach itself to the meat, and spoil the good appearance of it. It is not necessary to wrap meat or poultry in a cloth, if the pot be carefully skimmed. The general rule of the best cooks is to allow from 20 to 30 minutes slow simmering to a pound of meat, reckoning from the time the pot begins to boil. The cover of the boiling pot should fit close, to prevent the unnecessary evaporation of the water, and the smoke insinuating itself under the edge of the cover, and communicating to the boiled substance a smoky taste. Cooks often put a trevet, or plate, on the bottom of the boiling pot, to prevent the boiled substance sticking to the pot. _Rationale._--When flesh or fish is boiled in an open vessel, or one not closely covered, the fibrous texture is rendered more tender: at the same time its nutritive quality is not much diminished. For the temperature of the water or steam, never exceeding 212°, is insufficient to produce the partial charring, which roasting and broiling effect. But, as in stewing, the gelatine, albumen, osmazome, and fat, are developed and disengaged, and becoming united with the liquid in the vessel, form a soup, or broth. The paler colour of boiled meat is owing to the blood being separated and diffused in the water. In frying, the boiling fat or oil enters into the interstices of the fibres, which the disengaged animal juices have left empty. In boiling, in a similar way, the hot water takes the place of the blood, gelatine, fat, and albumen, which have been dissolved and separated from the fibres. The fibres are in this manner soaked and washed, first by the boiling water, and afterwards by the soup or broth which is formed, till the whole texture assume a softened consistence, and pale appearance. It is this, rather than any softening of the fibres themselves, which seems to be the real effect produced, unless, with some, we consider the fibres as nothing more than minute and close-set bundles of blood vessels. This doctrine, however, the experience of every cook will disprove; for if the boiling be long continued, the fibres of the meat will alone remain, and so far
