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 powdered 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.
