Brunost

Back home from 2 weeks away, empty fridge apart from a gift from Norway from son M . Brown sweet cheese- is it cheese? Can I cook with it?  
Made from cow and goat whey and boiled down to a caramelly brown mass.
Desperate for food I made it into cheese and potato pie - extra shows the brown stuff.  It did not melt like cheddar but tasted pretty good with onion and potato

Thank you very much for all the comments and stars from everyone who followed my Canadian adventure despite my lack of replies.
