Greek yogurt is a yogurt that has been strained to remove most of its whey, resulting in a thicker consistency than normal unstrained yogurt, while still preserving the distinctive sour taste of yogurt. Like many types, strained yogurt is often made from milk enriched by boiling off some water content, or by adding extra butterfat and powdered milk. In Europe and North America, it is often made from low-fat or fat-free cow's milk. In Iceland, a similar product named skyr is made. Strained yogurt is generally marketed in North America as "Greek yogurt" and in the UK as "Greek-style yogurt", though strained yogurt is also widely eaten in Levantine, Eastern Mediterranean, Middle Eastern, Central Asian and South Asian cuisines, where it is often used in cooking, as it curdles less readily when cooked. It is used in a variety of dishes, cooked or raw, savory or sweet.that has been strained to remove most of it Wikipedia
