When it comes to quirky-sounding seafood dishes, Jansson’s Temptation definitely makes the list.
Don’t worry – it’s not as scandalous as it sounds! This traditional Swedish casserole combines potatoes, cream, onions, and Swedish ansjovis (sprats) into a rich, comforting bake that’s surprisingly subtle and creamy.
Jansson’s Temptation: The story behind the name
As with all oddly-named seafood dishes, the origins of Jansson’s Temptation are a little mysterious.
Some believe the ‘temptation’ refers to how irresistibly tasty it is, while others claim the dish is named after the 19th-century opera singer, Per Janzon.
Meanwhile, the great Jane Grigson, in her must-have cookbook Jane Grigson’s Fish Book (available at Amazon), describes the name as an ‘incitement to culinary myth-making’.
She offers a more basic explanation, writing that with Jansson being a common Swedish surname, the dish could simply mean ‘Everyone’s Temptation’.
Whatever the true story, Swedes traditionally serve Jansson’s Temptation at Christmas – but its creamy, subtly salty flavour makes it perfect all year round.
How to make Jansson’s Temptation
The key to an authentic Jansson’s Temptation is using cream, not milk. As Jane Grigson warns:
“Don’t use milk instead of cream, or the beauty of the dish’s title will escape you.”
Thinly slice your potatoes and layer them evenly with onions and ansjovis – as per this recipe – for the perfect balance of creamy, soft potatoes and delicate fish flavour.
Tip: For a creative twist, try using lightly salted Atlantic herring in place of traditional sprats – it gives the dish a slightly different, but equally delicious, Nordic flavour.
