A guide to modern cookery

is the more suitable of the two. I pointed out above that the cooking of braised meat consists of two phases, and I shall now proceed to discuss each of these, so that the reader may thoroughly understand their processes. It has been seen that meat, to be braised, must in the first place be fried all over, and this more particularly when it is very thick. The object of this operation is to hold in the meat’s juices, which would otherwise escape from the cut surfaces. Now, this frying produces a kind of cuirass around the flesh, which gradually thickens during the cooking process until it reaches the centre. Under the influence of the heat of the surrounding liquor the meat fibres contract, and steadily drive the contained juices towards the centre. Soon the heat reaches the centre, where, after having effected a decomposition of the juices therein collected, the latter release the superfluous water they contain. This water quickly vaporises, and by so doing distends and separates the tissues surrounding it. Thus, during this first phase, a concentration of juices takes place in the centre of the meat. It will now be seen that they undergo an absolutely different process in the second. As shown, the disaggregation of the muscular tissue begins in the centre of the meat as soon as the temperature which reaches there is sufficiently intense to vaporise the collected juices. The tension of the vapour given off by the latter perforce increases by dint of finding no issue; it therefore exerts considerable pressure upon the tissues, though now its direction is the reverse of what it was in the first place, _i.e._, from the centre to the periphery. Gradually the tissues relax under the pressure and the effects of cooking, and, the work of disaggregation having gradually reached the fried surface, the latter also relaxes in its turn and allows the constrained juices to escape and to mix with the sauce. At the same time, however, the latter begins to filter through the meat, and this it does in accordance with a well-known physical
