Skyr is basically Iceland's yogurt product. It's like Greek yogurt, in that it's high in protein, but the flavor is more mild, and it's delicious. People in Iceland also use it in a lot of things. I had a Skyramisu, which a restaurant branded as tiramisu with a twist, and the twist was Skyr and cream cheese. As someone who is a huge fan of traditional tiramisu, I was pleasantly surprised with how delicious the Skyramisu was.
