Some years ago I tried Norwegian brown cheese Brunost. I am aware that technically it is not cheese and it is brown and very sweet due to caramelized milk sugar.  I was wondering - is there any other use of this cheese other than a sandwich with some butter and possibly jam/marmalade? 
Brunost is often used in Norwegian cooking, especially in brown sauces. E.g. like this.  I have personly used brunost for such a recipe, and it does add a very nice flavor to the sauce.  Here is a link to several recepies using brunost, from Tine the biggest maker of brunost in Norway)  Hope this helps, Best wishes from Norway!
