Easy Cold Poached Salmon

This Nordic dish of cold-poached salmon is a classic to serve at the solstice or any other summer celebrations. It’s an absolute breeze to make — and really punches above its weight in terms of flavor. Let’s find out more.

Super-Easy and Super-Impressive!

This is one of my go-to summer recipes for a dinner party, or any occasion where I want to make something elegant and impressive. At the moment of serving, all you need to do with cold-poached salmon is to slide it carefully out of the poaching liquid and onto the plate — leaving you free to concentrate on the side dishes, or to chat with your guests.

For a more informal gathering like a summer garden party, you can even bring the salmon to the buffet table still in its dish with the poaching liquid. That way it stays juicy and moist, even as people serve themselves.

It gets so much praise, that it’s almost embarrassing to share with people just how easy cold-poached salmon is to make!

Why I Love the Cold-Poaching Technique

This method of cooking fish is an absolute blessing for a busy cook who still wants to be proud of what she serves up. It’s a very easy technique, and it’s almost impossible to get it wrong. All you do is bring a pot of vinegared water with a little sugar and salt to a boil. Then pour the hot liquid over the salmon filets. We can add a few extra flavors to the pot with some herbs and spices, but really, it’s as simple as that.

The salmon gets zero direct heat and cooks in the hot liquid poured over it, absorbing more juice and flavor as it cools down. This means it’s impossible to overcook it, and you’re guaranteed perfectly poached, pink, juicy salmon every single time.

I have seen recipes that recommend putting the salmon into the pot of hot liquid, or even boiling it for several minutes before turning off the heat. But in my experience, these methods often end up cooking the salmon too much, or the filets end up a bit wonky-looking. Pouring hot liquid into the separate salmon dish is much more controlled.

Cold-poaching is also an incredibly versatile method. You can add different ingredients to the poaching liquid, to give a different flavor profile. And although Nordic salmon is the best-known dish to use this technique, it works for other types of fish as well.

And if you’re someone who’s sensitive to strong scents in your kitchen, cold-poaching is the way to go — with no pungent, lingering fishy smells hanging around the next day.

Where Does Cold-Poached Salmon Come From?

The cold-poaching method originated in the Nordic countries, especially in Sweden. It is thought to have originally been developed as a way to preserve fish. Historic recipes from the early twentieth century or before contain a lot more vinegar in the poaching liquid, which makes the mixture more acidic.

Acid inhibits the growth of harmful bacteria and molds, keeping the food safe to eat for a longer period. This type of preservation is called pickling and early cold-poached salmon recipes are probably more accurately described as pickled salmon.

The historic recipes usually call for white spirit vinegar, which is more acidic, and with a much sharper flavor. I’ve chosen to use a more delicately flavored vinegar, and far less of it. In this recipe, we’re not primarily using vinegar to preserve the salmon, but to add a welcome tanginess to the taste. But if you’re intrigued by the preservation history of the recipe, try adding more vinegar to the pot to experiment with a more acidic mix.

How to Prepare Salmon for Cold-Poaching

The most complicated part of this recipe is dealing with the raw salmon. You want a fat piece of salmon filet with the thin edge cut away. Ideally, also with the skin and any ragged edges trimmed away, and all bones removed.

If you have a good fishmonger, they will likely be able to handle all this for you. If not, read on!

Start by skinning the salmon. The easiest way is with a long serrated knife. A bread knife is ideal. Put the salmon skin side down on a chopping board. Start at one corner, cutting gently between the skin and flesh, until you have a small flap of skin that you can grip with your thumb and forefinger.

Insert the knife between skin and flesh, almost parallel with the chopping board, but angled slightly downwards with the serrated edge facing away from you. Pull the skin gently towards you as you slide the knife away from you with a gentle sawing motion from side to side. The skin should slide off easily in a single piece.

Trim away the thin part of the filet, and any ragged edges (save to make fish cakes!) Then run your finger along the top of the salmon filet to check for pin bones. If there are any, you’ll feel them as sharp little points sticking out. Grab them with tweezers and tug gently to remove.

Finally, cut your salmon into individual portions. It is much easier to cut it neatly when raw than to portion after poaching.

After that, all you need to do is heat up some lightly acidulated water to a boil, and pour it over! Super easy!

Ingredients

The most important ingredient in this recipe is of course the fish. It’s important to have a thick piece of salmon. Any thin floppy edges will cook through completely, and fall apart into flakes when you take them out of the liquid to serve. They will still taste good, but they won’t look great on the plate.

It’s also important to get fish as fresh as possible. It’s better to make cold-poached salmon with defrosted raw fish filets than to use fresh salmon which has been hanging around at the fish counter for several days.

This technique should work well for almost any filet of fish, so feel free to experiment! Just be aware that thinner filets or fish with a very fine texture will be much more delicate to handle, and harder to keep whole in nice neat portions.

And if you want to change up the flavors, go right ahead! Keep the amount of water, acid, sugar, and salt roughly the same, but you can try different herbs and spices, like:

• Italian Salmon: Use balsamic vinegar, orange instead of lemon, a few slices of fresh fennel, and some capers for a Sicilian twist.
• Chinese Poached Salmon: Try rice vinegar, soy sauce, scallions, fennel seeds, a whole star anise, and a cinnamon stick in the poaching liquid. Drizzle a little sesame oil over it on the serving plates.
• Peruvian Salmon: Take inspiration from ceviche by adding lots of lime juice instead of vinegar, fresh hot chili, cilantro, and red onions. Great served with an avocado salad!

Storage

Store in the fridge in the poaching liquid until ready to serve. It should stay good for up to two days, or even longer if you increase the amount of vinegar.

This salmon recipe is too delicate to freeze well. You will get a better result freezing the portioned and prepared raw salmon, then defrosting and poaching it when ready to cook.

And More…

I most enjoy this cold-poached salmon as a cold entrée, served with my Radish, Cucumber, and Dill Salad. If I’m feeling extra hungry, I might make a batch of Pumpkin Potato Latkes as well.

But if I’m feeling lazy, more often than not I will just serve it with simply steamed asparagus, haricots verts, or plain boiled baby potatoes.
