Greek Yoghurt often referred to as Strained yogurt,
Greek-style yogurt, yogurt cheese, sack yogurt, kerned yogurt or labneh
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.
