Escoffier Recipe 13
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; hence their utility is nil if the stock which they are intended to finish has been reasonably and judiciously treated. It is infinitely simpler to 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.
