Apparently it's a common problem for people who move to Denmark that most cartons that look like they contain milk or juice actually contain yogurt. "This has fruits on it. Surely this is juice" Nope, fruity yogurt. "The stuff that comes out of this carton is super runny. Surely this is milk" Nope, runny yogurt. Danes love yogurt.
Hint, look for the word "mælk". It might say Minimælk, Sødmælk, Skummemælk and so on, but if the letters "mælk" are in there somewhere you can be relatively sure it's milk. I have seen yogurt milk too though, so be careful.
