Soft whey-cheese is sold by the pan in Medelpad. In Dalarna and Medelpad some people keep their cattle 80 to 100 miles away in the mountains because there are wasps and mat-grass low down. They have milking booths up there. When cheese is being made, the whey is boiled and rendered down by 2/3 until it goes like porridge. This is sometimes eaten as butter, sometimes a little of it is mixed in with dough, sometimes it is used in other ways.
