Greek yogurt is a yogurt that has been strained to
remove most of ites whey, resulting in 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.
