Greek yogurt is a yogurt that has been strained to
remove most of it whey, resulting in a thicker consistency
than unstained 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 powdered milk. In Europ and North
America, it is often made with low-fat or fat-free yogurt.
In Iceland a similar product named skyr is produced.
