As used in Quail egg and prawn set in aspic molds
Clarified stock is used for clear soups and savory jellies. During the clarifying process a certain amount of flavor will be lost. To avoid this, add additional finely chopped aromatic vegetables (vegetables, celery, leek, parsley, etc) together with the specified amount of gelatin to the stock. Then add lightly whisked egg white (2 or 3 depending on the volume of the stock) and bring the stock up to the boil. The egg white will start to form a crust on top to which all the impurities (that make the liquid cloudy) in the stock get trapped. Do not stir the stock at all. This process will take about ten minutes after boiling started, then turn the heat of and carefully remove the crust. Through a sieve lined with double cheesecloth and over a large bowl, slowly ladle the stock through. Do not squeeze the cheesecloth or force the liquid through. The stock is now clarified. Seasoning are added then to flavor the aspic according to the recipe of the dish you are preparing.
