What is it?? ......
Well milk is made up of casein and
whey. Casein is what curdles and is used
to make cheese and yogurt, while whey is the watery substance left when
the milk curdles. So what is Greek yogurt? Greek yogurt is essentially
the same as regular yogurt with the addition of one critical step –
straining! At the very end, the yogurt is strained to remove the excess
watery whey, creating a thicker, more protein-dense product. So while we
call this variation of yogurt “Greek yogurt” in the U.S., you may see it
called “strained yogurt” in other areas of the world.
