The Time Required for Boiling Down Soup or Stock

This must be regulated by several considerations; for though the mere juices of meat require but little boiling after they have been fully extracted by the slow heating recommended by Baron Liebeg, soup to which many vegetables are added (winter vegetables especially) requires long stewing to soften and to blend properly the flavour of all the ingredients which it contains, as that of no one in particular ought to be allowed to predominate over the rest. We have in consequence retained the old directions as to time, in many of the following receipts; but an intelligent cook will soon ascertain from practice and observation how and when to vary it with advantage. Over-boiling renders all preparations insipid, and causes undue reduction of them likewise: it is a fault, therefore, which should be carefully avoided.
