Icelandic yogurt or Skyr is mildly tangy and noticeably thicker than
Greek yogurt. There is a debate on whether Skyr should be considered a
variety of yogurt. Because the process allows curds to form, it can be
argued that it is a cheese. Whatever Skyr technically is,
it is consumed like a yogurt, and so it is marketed as
Icelandic yogurt to Americans. Skyr is strained four times, creating one
of the thickest consistencies of yogurt available.
