Skyr is an Icelandic dairy product. I've heard it compared to yogurts and cheeses. It has a consistency close to Greek Yogurt, but the flavor is different. I find it in grocery stores in the United States. I am fond of a brand called Siggi's. They make it in the USA but say they base it on Scandinavian dairy traditions. I tend to prefer the flavors when they have a higher fat content. Also, I prefer to have it with something, for example on crackers.
