I'm sure that it is. (delicious) I looked up Lingonberries and I don't know why more of them aren't grown here -- especially in northern climes like where we live. They are related to the cranberry and grow on little bushes that look a lot like miniature boxwood. I think they would make a delightful border plant, except that the deer around here would probably demolish them.
Outside of Sweden, they are grown Minnesota and Canada mostly. They are a staple of Swedish cooking.
....that look will wake up the office.
