These Creamed Cod (fish) Roes are in fact not a traditional product.
I think they were invented in the 1930's. or during WW2 when it was difficult to ship foods to Sweden?
I have also been told that it was a way to get the healthy fish oil into children.
The standard was rancid Cod Liver oil. ( rancid because people did not have fridges in those days) .
The Salt and sugar cure ( plus smoking for some brands) acts as a preservative, so a tume of this breakfast spread could be kept in the pantry, opened, for a week or so.
Wife is a rabid lover, so we bring it back from Norway. Not this brand though.
On weekend walks I used to carry a tube or two of Kavli ( preferable Shrimp) which is another superb Swedish food product that lasts well.
British Cheddar is superb too, lasts just fine.
Do that with Brie or Camembert...... OK for one day. Just.
Many hard cheeses dry out and become tooth breakers after a few days, but not Cheddar.
