This is a classic Swedish recipe, something we would put into the husmanskost category. Husmanskost is basically what we'd call your classic day to day dishes, what you'd expect to get at school or at one of the many lunch restaurants that are around.
Fransk is Danish, as well as Swedish and Norwegian, for French. For me this little meal is very closely associated with Denmark and I guess the lesser Swedes as I call them called it French Hotdog due to the fact that it is served in a baguette.
This dish didn't really have an recipe when I started. It was cooked from distant memories, we're talking 30 years or so since I last had it. In the end it didn't end up too far from being how I remembered it.
