Introduction: “Jansson’s Temptation” is a creamy baked casserole of potato and pickled sprats, a must-have on the Swedish Christmas smörgåsbord (julbord).
Cultural Background: “Jansson’s Temptation” is a creamy baked casserole of potato and pickled sprats, a must-have on the Swedish Christmas smörgåsbord (julbord). Its origins are debated, but its place at the holiday table is not.
Tips: Cut the potatoes into thin, even matchsticks so they cook through evenly. Use genuine Swedish ansjovis (sprats), not Mediterranean anchovies, for the correct sweet-cured flavour.
Variations: A vegetarian version omits the sprats and adds extra caramelised onion and a touch of smoked paprika for depth, though this departs from the traditional dish.
Storage: Refrigerate in an airtight container for up to 2 days.
Reheating: Reheat in the oven at 180°C (350°F) for 15–20 minutes until hot through.

FAQs:
Q: Can I substitute regular anchovies?
A: The flavour will be saltier and sharper — Swedish sprats are milder and slightly sweet, giving the dish its characteristic taste.
Q: Is it served as a main or a side?
A: Traditionally a side on the Christmas smörgåsbord, though it’s hearty enough to serve as a light main.
