This lovely salmon soup from Iceland is something of a cross between a chowder and a soup, with just a touch of dairy. It’s warming and comforting without being overly heavy, which I like. And what’s more, it can be made quite well with the meat left on the racks of salmon or trout, so you waste less.
I got the idea for this salmon soup from the awesome cookbook Icelandic Food & Cookery
by Nanna Rögnvaldardóttir. Iceland still has good populations of Atlantic salmon, but of course, being in California, I use our local chinook salmon instead. Any salmon or large trout, or several smaller trout, will work for this recipe.
You start by making a broth with the salmon bodies. I know, most cooks will tell you not to do this because salmon broth will be strongly flavored. But this is a salmon soup, and you’re not storing the broth for more than a couple days, so you won’t get that awful “salmon stink” everyone knows and hates.
I also have a separate recipe for salmon stock, which you can also use if you want.
After the salmon makes the broth, you pick off the leftover meat and reserve that for the finished soup. A few root vegetables or potatoes go in, and when they’re done, add a little cream, a few fresh herbs, and you’re good to go.
There is one special ingredient that really makes this salmon soup, however: whey. This tart byproduct of cheesemaking adds the brightness that this soup needs — it’s a common ingredient in Nordic cooking, one I’d love to see more Americans use.
How to get whey? Easy. Buy some milk and make some homemade ricotta cheese. (Here’s how to make ricotta cheese at home) You can then use your ricotta any way you’d like, but I might suggest using it in venison lasagna.
Of course, you can skip the whey if it’s too much trouble. But it does make this salmon soup special.
Everything else is easy to find and uncomplicated. This is, actually, something of a chowder — although I have a Pacific Northwest rendition of salmon chowder elsewhere on this site.
Icelandic Salmon Soup
Ingredients
SALMON BROTH
- Head and bones from a large salmon, about 3 pounds of bones and meat
- 2 carrots, chopped small
- 1 small onion, chopped small
- Stems from a bunch of parsley, chopped
- Stems from a bunch of dill, chopped
- Stems from a bunch of lovage, chopped (optional)
- 2 bay leaves
- 2 cups whey (optional)
- 1 quart water
- Salt
SOUP
- 2 tablespoons butter
- 1 small onion, sliced thin
- 1 pound small potatoes
- 1 pound salmon meat
- 1/2 cup mixed chopped fresh herbs, like parsely, dill and lovage
- 1/2 cup heavy cream
- 2 egg yolks, lightly beaten
- black pepper to taste
Instructions
- Bring all the broth ingredients to a boil in a large pot. Drop the heat below a simmer and let this cook gently for 30 to 45 minutes. Strain and keep warm. Pick off salmon meat and reserve.
- In a soup pot, heat the butter over medium-high heat and cook the sliced onion until wilted and transparent, but not browned.
- Pour in the broth and potatoes, bring to a simmer and add salt to taste. Simmer gently until the potatoes are tender.
- Add the salmon, either picked from the bones or freshly diced, plus the herbs and heavy cream. Let this simmer 5 minutes.
- With a ladle in one hand and a whisk or fork in the other, slowly ladle some hot broth into the egg yolks, all the while whisking the egg yolks. You want to temper them so the yolks won't curdle in the soup. Whisk in another ladle, then one more. Pour this into the soup, stir well and turn the heat as low as it will go. Let this warm up a minute or three, then serve at once.
can this be froxen
Susan: Not with the cream in it. You could make it without the dairy, freeze, thaw and then add it when you are ready to eat.
Just to clarify, do you use sour/acid why or sweet whey?
Doing some research about the type of whey produced when making ricotta I’ve come to the conclusion that it is acid whey.
I just put it in the soup so we’ll see in 2 hours..
Timmy: I use the whey leftover from making cheese, so I guess it’s acidic.
We just got home from visiting Finland and I wanted to make the salmon soup we had in Lapland. This was perfect. The salmon broth and herbs makes it so wonderful…and the egg yolks at the end of the recipe! We loved the soup with a hot loaf of crusty sourdough bread.
Not so special. The soup taste good, but i can not tell what the uniqe iceland flavor is.
There is no special Icelandic signature flavor. If anything it is the clean taste of the main ingredients, with very little in the way of spices except for salt or pepper. Sour cream from either cow’s or sheep milk might be close to a signature flavor, but this traditionally was a luxury food, and traditionally available for regular consumption at the summer hills farms up in the mountains of Norway. This summer farms took advantage of summer grazing that couldn’t be utilized otherwise. I expect it would be the same on Iceland. That they would set up a cottage and young women or even children would mind the animals and produce sour cream, cheeses and also cook brown “cheese” from the whey. Sour cream has a much longer shelf life than fresh cream. It is like a Scandinavian yoghurt.. sort of ..
We made it with trout, it was excellent! Thanks for the recipe!
Also that Yogurt will change to Cream Cheese with tuffy’s method
re: whey:
one can also make whey + greek yoghurt by simply pouring a quart or two of regular yoghurt into a cheese-cloth covered sieve and let the whole thing drain into a pot over night. you’ll get greek yoghurt up top and whey in the bottom pot.. 🙂
Tuffy: Nice! Thanks for the tip.
Hank,
We make our own cheese regularly (Formage Blanc) and are drowning in Whey. I’d love to see a post with good ideas for it’s use.
Aaron: Well, there’s this one, and the Russian pelmeni dumplings I make, too. And real ricotta is made from whey.
