It's commonly eaten for breakfast in Norway in a variety of ways. You could probably get it anywhere with a scandanavian community.

Seriously, though, I'll have to find a way to try it. It looks delicious!
Checking Amazon, it looks like they sell it (though they call it "gjetost"), and the price isn't too bad. I might have to get some.
Though apparently it's high in fat and sugar, so it will have to be consumed in very small amounts.
