Top-ranked recipe named "Jansson's Temptation"
This is a traditional Swedish dish often found as a part of a smorgasbord, especially around the holidays.
A note regarding anchovies. Anchovies found in most supermarkets are the Spanish variety. The Spanish variety can be used and it comes out pretty good, although somewhat saltier. For authenticity, Swedish anchovies should be used. I know that unless you live in Sweden, it may be difficult to find, but if you live near an Ikea store, you can usually find Swedish anchovies in the Swede shop found at most Ikeas world wide. Another variation is to use Swedish caviar instead of anchovies. Swedish caviar is cod roe which comes in tubes and can also be found at Ikea.
