My father would eat pickled herring all of the time, I could never look at the stuff … but pickled herring certainly wasn’t lutfisk.
My mother made cookies called pepperkakker. It was a gingerbread cookie and I could eat a dozen of them in one sitting.
We would have something my family called Korv at Christmas time which was a potato sausage. The version of the sausage we ate had a very unique flavor and I found out much later in life that cardamom was one of the ****es used to make it. Cardamom is great in breads but in my opinion, an acquired taste in savory. (as a side note, nobody from NJ had ever heard of it but everybody from Jamestown, NY, a Scandinavian stronghold and my place of birth and place of residence for the first six months of my life, claimed it was a traditional Swedish dish. But since moving out here to MN I have not heard anybody refer to the sausage as “Korv” … I suspect the sausage is truly a traditional Swedish dish but the name “korv” is an American invention)
