Put the Stock-pot on a Gentle Fire, so that it may heat gradually. The albumen will first dissolve, afterwards coagulate; and as it is in this state lighter than the liquid, it will rise to the surface, bringing with it all its impurities. It is this which makes the scum. The rising of the hardened albumen has the same effect in clarifying stock as the white of eggs; and, as a rule, it may be said that the more scum there is, the clearer will be the stock. Always take care that the fire is very regular.
Remove the Scum when it rises thickly, and do not let the stock boil, because then one portion of the scum will be dissolved, and the other go to the bottom of the pot; thus rendering it very difficult to obtain a clear broth. If the fire is regular, it will not be necessary to add cold water in order to make the scum rise; but if the fire is too large at first, it will then be necessary to do so.
When the Stock is well Skimmed, and begins to boil, put in salt and vegetables, which to every 3 lbs. of meat should consist of three carrots, two turnips, one parsnip, a few leeks, and a little celery. You can add, according to taste, a piece of cabbage, two or three cloves stuck in an onion, and a tomato. The latter gives a very agreeable flavour to the stock. If burnt onion be added, it ought, according to the advice of a famous French chef, to be tied in a little bag: without this precaution, the colour of the stock is liable to be clouded.
By this time we will now suppose that you have chopped the bones which were separated from the meat, and those which were left from the roast meat of the day before. Remember, as was before pointed out, that the more these are broken, the more gelatine you will have. The best way to break them up is to pound them roughly in an iron mortar, adding, from time to time, a little water, to prevent them getting heated. It is a great saving thus to make use of the bones of meat, which, in too many English families, we fear, are entirely wasted; for it is certain, as previously stated, that two ounces of bone contain as much gelatine (which is the nutritive portion of stock) as one pound of meat. In their broken state tie them up in a bag, and put them in the stock-pot; adding the gristly parts of cold meat, and trimmings, which can be used for no other purpose. If, to make up the weight, you have received from the butcher a piece of mutton or veal, broil it slightly over a clear fire before putting it in the stock-pot, and be very careful that it does not contract the least taste of being smoked or burnt.
Add now the Vegetables, which, to a certain extent, will stop the boiling of the stock. Wait, therefore, till it simmers well up again, then draw it to the side of the fire, and keep it gently simmering till it is served, preserving, as before said, your fire always the same. Cover the stock-pot well, to prevent evaporation; do not fill it up, even if you take out a little stock, unless the meat is exposed; in which case a little boiling water may be added, but only enough to cover it. After six hours’ slow and gentle simmering, the stock is done; and it should not be continued on the fire longer than is necessary, or it will tend to insipidity.
Note.—It is on a good stock, or first good broth and sauce, that excellence in cookery depends. If the preparation of this basis of the culinary art is intrusted to negligent or ignorant persons, and the stock is not well skimmed, but indifferent results will be obtained. The stock will never be clear; and when it is obliged to be clarified, it is deteriorated both in quality and flavour. In the proper management of the stock-pot an immense deal of trouble is saved, inasmuch as one stock, in a small dinner, serves for all purposes. Above all things, the greatest economy, consistent with excellence, should be practised, and the price of everything which enters the kitchen correctly ascertained. The theory of this part of Household Management may appear trifling, but its practice is extensive, and therefore it requires the best attention.
