In cooking, a consommé is a type of clear soup made from richly flavoured stock or broth that has been clarified, a process that uses egg whites to remove fat and sediment.
A special type of consommé that was boiled solely with tendons and cartilage without the addition of salt was sweetened, flavoured with fruits and served as dessert.
A consommé is made by adding a mixture of ground meats, together with mirepoix (a combination of carrots, celery, and onion), tomatoes, and egg whites into either bouillon or stock.
If beef or veal is used, shin meat is ideal[4] because it is very low in fat and very high in gristle, and although it is undesirable for most other purposes, it is near essential for the flavour of the consommé.
The liquid is then carefully drawn from the pot and passed again through a filter to ensure its purity, and is then put through a lengthy process where all of the visible fat is skimmed from the surface.
They are most often served with garnishes, which vary in complexity from a simple splash of sherry or egg yolk, to cut vegetables, to shaped savoury custards called 'royales'.
[8] In a 2007 New York Times article,[9] Harold McGee popularized an alternative method for clarifying broths, originating among chefs of the molecular gastronomy movement: gelatin filtration.
Gelatin-filtration is a novel method of clarification, relying on some of the properties of a super-saturated solution of gelatin, created by freezing, to remove macroscopic particles that cause cloudiness from a water-based stock.
This stable network acts as a filter, trapping large particles of fat or protein, while allowing water and smaller, flavor-active compounds to pass.
