Stocks should be clear and not cloudy, so never boil too rapidly, just to a light boil or simmer. If reduced down to 1/3 of original volume, stocks are then called demi-glacé or glacé de viande. These methods are being phased out due to labour cost and better powdered bases. White and brown stocks, which used to be essential bases for almost all the great classic sauces, take a very long time to make and are often expensive, even though it is a good way to use up some kitchen scraps. They can be used in a thickened or unthickened form. They are also based on veal, beef, poultry, game, vegetables, fish, or aromatic ingredients. Other basic cooking stocks include velouté, consommé, essence, aspic, marinade, matignon, court-bouillon and brine.
There are three main stocks.
For the most part stocks are aromatic but not salty, since they have to remain unseasoned until they are finished in their final form, or used in a soup or sauce for example. Nevertheless, just an optional pinch of salt enhances the blending of the ingredients and the liquid. After the stock is cooked the meats can then be used to make different recipes such as, purée, stuffings, etc. When they said nothing goes to waste, they meant it here.
