Janssoninkiusaus (lit. ‘Jansson’s temptation’) is a Swedish traditional dish that was long only known as a night-time snack. Nowadays it has its place in the Swedish Christmas menu as well.
Several options have been suggested as the origin of the name ‘Janssoninkiusaus’, but no one knows with certainty. Some have thought the dish was named after the Swedish opera singer Per ‘Pelle’ Janzon (1844–1889). Janzon used to invite his friends and colleagues to his home for a night-time snack after the evening’s show, often serving a gratin made of potatoes, onions, anchovies and cream. According to different sources, the dish was developed either by Janzon in the 1800s or by Elvira Stigmark from Stockholm in the 1920s. Another theory is that the dish was named after the Swedish movie Janssons frestelse that premiered in 1929.
A third legend has it that the name originates from a Swedish sectarian preacher, Erik Jansson, who lived in the United States in the 1800s. After falling out with the authorities and the church of his home country, Jansson took his congregation and went into exile in Illinois, America. Once there, he founded a communist community called Bishop Hill. While strictly abstinent in every other aspect, he had one weakness: a delicacy dish made of potatoes, anchovies, onions and cream.
In any case, it is a classic dish from Sweden.
The Swedes fall into temptation on Christmas: janssoninkiusaus is a traditional part of the Swedish Christmas menu.
Janssoninkiusaus is prepared by shredding the potatoes, piling them up in layers with anchovies on a pan, and pouring double cream seasoned with anchovy stock on top. The original janssoninkiusaus is prepared with the so-called Scandinavian anchovy, i.e., seasoned European sprat.
