13— VARIOUS ESSENCES
As their name implies, essences are stock which hold a large proportion of a substance's aroma in a concentrated form. They are, in fact, ordinary stock, only less diluted, with the idea of intensifying the flavour of the treated ingredients r hence their utility is nil if the stock which they are intended to finish has been reasonably and judiciously treated. It is infinitely simpler ta make savoury and succulent stock in the first place than to produce a mediocre stock, and finally complete it by a specially prepared essence. The result in the first instance is better, and there is economy of time and material.
The most one can do is to recommend, in certain circumstances, the use of essences extracted from particularly well-flavoured products, as, for instance, mushrooms, truffles, morels, and celery. But it would be well to remember that, nine times out of ten, it is preferable to add the product itself to the stock during the preparation of the same than to prepare essences.
For this reason I do not think it necessary to dilate upon the subject of essences, the need of which should not be felt in good cooking.
14— VARIOUS GLAZES
The various glazes of meat, fowl, game, and fish are merely stock reduced to the point of viscosity. Their uses are legion. Occasionally they serve in decking dishes with a brilliant and unctuous coating which makes them sightly; at other times they may help to strengthen the consistence of a sauce or other culinary preparation, while again they may be used as sauces proper after they have been correctly creamed or buttered.
Glazes are distinguished from essences by the fact that the latter are only prepared with the object of extracting all the flavour of the product under treatment, whereas the former are, on the contrary, constituted by the whole base of the substance itself. They therefore have not only its savour, but also its succulence and mellowness, whereby they are superior to the essences, and cooking can but be improved by substituting them for the latter. Nevertheless, many chefs of the old school do not permit the use of glazes in culinary preparations, or, rather, they are of opinion that each cooking operation should produce them on its own account, and thus be sufficient unto itself. Certainly, the theory is correct when neither time nor cost is limited. But nowadays the establishments are scarce where these theories may be applied, and, indeed, if one does
