Greek yogurt is a yogurt that has been strained to remove most of its whey,
resulting in a thicker consistency than unstrained yogurt, while preserving
yogurt's distinctive sour taste. Like many types of yogurt, strained yogurt
is often made from milk that has been enriched by boiling off some of its water
content, or by adding extra butterfat and powedered milk. In Europe and North
America, it is often made with low-fat or fat-free yogurt. In Iceland a similar
product named skyr is produced.
