Jansson's Frestelse

This is a gratin-style dish that everyone in Sweden knows well. Never make the mistake of using anchovies, as many English-language recipes suggest. The Swedish word ‘ansjovis’ actually means sprats, not anchovies. Whoever originally translated it that way condemned many a poor person to a very salty dish!

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

Flavor stand-ins for the onion

How well each one fits the dish's main ingredients (potato, butter, cream, milk):

  1. Onionthe original
  2. Asparagusabout as good a flavor fit
  3. Leekabout as good a flavor fit
  4. Chiveabout as good a flavor fit

Fit is the average pairing score against potato, butter, cream, milk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
