For those unfamiliar with this Jansson's Temptation (as I was a few short days ago) it's a potato and onion casserole-like dish which contains Swedish anchovies, aka sprats. It's a bonus that our new dish to try contains seafood - no doubt a pleaser for my kids. Unfortunately, yes, as I sit here typing after assembling and putting this in the oven, my fingers decidedly smell like pickled sprats. Hopefully seventeen more washings will erase that aroma. (Note: it only took four.)
There seemed to be several variations of this recipe around the web. But the one I made was (more or less) followed exactly from Rebecca, who claims authenticity through her Finnish husband. My kids thought it was a hit. Spencer declared Jansson's Temptation to be "AWE-SOME!" and Charlotte was fascinated with the crisp bread.
from Kaarle & Rebecca Rautio
2 large baking potatoes (peeled and cut into matchsticks)
1 large onion (diced small or sliced thin)
1 1/2 - 2 Cups cream
1 tin Swedish anchovies (diced, reserve liquid)
1 tomato (sliced)
salt & white pepper
Chop the potatoes into matchsticks and dice the onion. Put all of this into a bowl and combine well.
Pour half of the potato/onion mix into a well-buttered casserole dish. Layer with diced anchovies. Season with white pepper and a bit of salt, if you like. Dot with butter (cut into small pieces). Pour remainder of potatoes on top. Again, add a little white pepper and salt, if you like.
Pour anchovy "juice" over casserole and then pour cream over. Liquids should be about half the depth of the dish. Place slices of tomato on top of casserole, dot with butter and sprinkle with bread crumbs.
Cover with foil and bake for about an hour. Uncover and bake just a bit more to let top become brown.
In traditional style, you must serve this with some dark rye bread, butter, sliced cheese (for the bread), and a nice green salad! Hyvaa Ruokahalua! (Enjoy your meal!)
