Skyr, from Iceland, is really a kind of yogurt. Now, instead of having to fake it with buttermilk or other types of dairy ingredients, you can actually make it yourself easily. Why? Because it is available here in the US of A as Siggis... cost you over a buck for a small container but you can use that as the start of a great relationship with Skyr (pronounced "Skeer") Since you will need only part of the container, just freeze the rest - I use a melon ball scoop to take out portions and place each in a small plastic sandwich bag and label it and freeze it for future use. And oh yes, a yogurt maker makes it easier to make the yogurt - we have a Waring Pro Yogurt Maker we bought several weeks ago. A thermometer is really needed here - one that gets you from room temperature or below to at least the boiling point. And you should be able to tell when the temperature is below 100F, at or above 190F, and at 110F. Those temperatures are critical to most yogurt making.
Also, we sometimes mix the result with a teaspoon or so of jam per serving - strawberry is good. And the resulting yogurt can be used for many, many different things. This is not your parents yogurt!
