Literally translated, it means "old cheese." Through the years, I've come to understand it means "stinky," "indelible," and other such adjectives as described my particular Norwegian family. My mom claims that the one time she bought it for my dad (a Norwegian immigrant), it stunk so badly that she couldn't leave it in the trash--she had to bury it in the back yard.
Given my enjoyment of many stinky cheeses, I am thinking I may have missed out by not trying this the times we visited family in Norway.
Anyone have any experience with Gammelost? And if so, your thoughts?
