Veal is the meat of a young cattle (calf). Though veal can be produced from a calf of either sex and any breed, most veal comes from male calves of dairy cattle breeds. Compared to beef, veal has a delicate taste and tender texture There are four types of veal: Bob Veal, from calves that are slaughtered a few days after birth, when they weigh 150 lb. (USA only) Formula-Fed (or "milk-fed") veal, from calves that are raised on a nutritionally complete milk formula supplement. The meat colour is ivory or creamy pink, with a firm, fine and velvety appearance. Usually slaughtered when they reach 18â€“20 weeks of age (450-500 lb).  Non-Formula-Fed ("red" or "grain-fed")  veal, from calves that are raised on grain, hay or other solid food in addition to milk. The meat is darker in colour, and some additional marbling and fat may be apparent. Usually marketed as calf rather than veal at 22â€“26 weeks of age (650-700 lb). RosÃ© Veal UK is from calves reared on farms in association with the UK RSPCA's Freedom Food programme. Its name comes from its pink colour, which is a result of the calves being slaughtered at around 35 weeks.  The veal industry's support for the dairy industry goes beyond the purchase of surplus calves. It also buys large amounts of milk by-products. Almost 70% of veal feeds (by weight) are milk products. Most popular are whey and whey protein concentrate (WPC), by-products of the manufacture of cheese. Milk by-products are sources of protein and lactose. Skimmed milk powder, casein, buttermilk powder and other forms of milk by-products are used from time to time Veal has been an important ingredient in Italian and French cuisine since ancient times. The veal is often in the form of cutlets, such as the Italian cotoletta or the famous Austrian dish Wiener Schnitzel. As veal is lower in fat than many meats, care must be taken in preparation to ensure that it does not become tough. In addition to providing meat, the bones of calves are used to make a stock that forms the base for sauces and soups such as demi-glace. The stomachs are also used to produce rennet, used in the production of cheese. Stock is a flavoured liquid. It forms the basis of many dishes, particularly soups and sauces. Stock is prepared by simmering various ingredients in water, including some or all of the following: Meat Leftover cooked meat, such as that remaining on poultry carcasses, is often used along with the bones of the bird or joint. Fresh meat makes a superior stock and cuts rich in connective tissue such as shin or shoulder of beef or veal are commonly recommended, either alone or added in lower proportions to the remains of cooked poultry to provide a richer and fresher-tasting stock. Quantities recommended are invariably in the ratio of 1 part fresh meat to 2 parts water. Pork is considered unsuitable for stock due to its greasiness (although 19th century recipes for consomme and traditional aspic invariably included slices of mild ham) and mutton was traditionally avoided due to the difficulty of avoiding the strong tallowy taint imparted from the fat. Bones Veal, beef, and chicken bones are most commonly used. The flavour of the stock comes from the cartilage and connective tissue in the bones. Connective tissue has collagen in it, which gets converted into gelatin that thickens the liquid. Stock made from bones needs to be simmered for longer than stock made from meat (often referred to as broth). Pressure cooking methods shorten the time necessary to extract the flavour from the bones. Mirepoix A combination of onions, carrots, celery, and sometimes other vegetables. Often the less desirable parts of the vegetables (such as carrot skins and celery ends) are used since they will not be eaten. Herbs and spices The herbs and spices used depend on availability and local traditions. In classical cuisine, the use of a bouquet garni (or bundle of herbs) consisting of parsley, bay leaves, a sprig of thyme, and possibly other herbs, is common. This is often placed in a sachet to make it easier to remove once the stock is cooked. Broth is very similar to stock, and often the terms are used interchangeably. Usually, broth refers to finished product, while stock is used as an ingredient (thus stock may become broth). Other times, broth is used to refer to a liquid made in the same way as stock, but meat is substituted for bones. However, with some stock/broth made from vegetables and some made from both bones and meat, this cannot be considered a hard-and-fast rule. Today, ready-made stock and stock cubes consisting of dried, compressed stock ingredients are readily available. These are commonly known as bouillon cubes (or oxo cubes, after a common brand of stock cube sold in Britain) or cooking base.
