Unless other wise specified, the world “milk” refers to cow’ s milk. Milk is usually sold pasteurized and homogenized. It is key ingredient in the cuisines of many Western countries, but is consumed less widely in Asia and Africa. Milk is an excellent source of protein and few foods provide as much calcium. Milk is also rich in phosphorus and potassium and it contains an essential fatty acid, linoleic acid. Nevertheless while the last decades there has been a lot of controversy concerning the dietary value of milk, it’s culinary value remains undisputed since it is a staple to many preparations.
