Smoked salmon is one of the great joys of life! In my opinion, one of the best types is cold smoked salmon.
It is the perfect accompaniment to a platter, great with eggs benedict or just fantastic on a cracker with cream cheese.
The possibilities are endless and I am yet to come across a combination that I don’t like.
The process of cold smoking salmon is actually surprisingly easy and is something that I wish that I had come across earlier in my smoking career.
My whole family is obsessed with the homemade version! Someone is always asking me to make it.
I love creating it, but it does take time, a little bit of know-how and a couple of special pieces of equipment.
I often get asked a lot of questions about how to cold smoke salmon and just the basics so I will cover that here 🙂
There are a few things about cold smoking salmon that you should know before you start:
- Closely Watch Your Temps: Don’ t let your smoker reach a temperature of over 80 degrees Fahrenheit. This will end up cooking the salmon and you will come away with a different result than desired.
- Yep, Its Still Raw Fish: Cold smoked salmon is technically still raw, however, the curing process allows you to eat it. This is because the highly saturated brine causes the proteins in the salmon to denature.
- The Necessary Equipment: To cold smoke salmon (or any other fish) you need a smoker that can be set up for cold smoking. So either pick one up or have to head over to your friend’s house who has a cold smoker.
Should I Be Using Fresh or Frozen Salmon?
It may come as a surprise to you but frozen salmon is actually better to smoke with than fresh. This is because the freezing process does two things:
- Kills Any Parasites: Salmon can have harmful parasites throughout the fillets. The best way to kill the parasites is to deep freeze them at -10 degrees.
- Ruptures the Cell Membranes: During the freezing process, the liquid inside the cells expands. This puts more pressure on the cell walls and causes ruptures.
Once the walls have been ruptured and the salmon starts to thaw, the liquid from inside the fillets drains from the flesh. This means there is less water for the brine to remove.
What Type Salmon Should I Use For Cold Smoking Salmon?
Now you know you should be using frozen salmon, what kind of salmon should you use?
Choosing your salmon is very important. There are plenty of different kinds of salmon out there, but what one is right for smoking?
The Best Type of Salmon for Smoking
The best type of salmon for smoking is sockeye salmon & King salmon (Chinook salmon). It is not imperative that you use one of these cuts, however, for you seafood lovers out there it will be well worth it!
How To Cold Smoke Salmon
Prepare Your Salmon For Cold Smoking
- Scale Your Salmon: To scale the salmon run the backside of a knife over the skin and rub up and down to de-scale the skin. Rinse to get all scales off and repeat as needed.
- De-Bone: To de-bone the salmon, you will need a pair of needle nose pliers. It is possible to do this by hand but it is much, much harder.
To find the bones, run your hand down the fillet and when you find a bone pull firmly with a pair of needle nose pliers to remove. The bones are evenly spaces running the length of your fillet from head to tail.
I usually double check a second time after finishing to make sure I have got every last bone!
- Cutting The Salmon: If you have a large smoker, leaving the fillet whole is ideal, however, for smaller smokers, I recommend cutting into chunks. Either way, make sure you leave the skin to prevent the fillet from falling to pieces.
Each cut or fillet of salmon is slightly different in size and thickness. The bigger the fleet the longer it will need to brine and smoke. This is because there is more flesh for the brine and smoke to get through.
You can speed up the process by making scores into the fillets. Be sure not to score the flesh too deeply.
Brine Your Salmon Fillets?
The brine is your next step and very important. It is a very delicate process and one that you should take a lot of care while doing. Essentially, the better you brine – The better your final result will be.
Here are some of my top tips to remember when brining your salmon:
- You must make sure that the brine is over 35 degrees and under 40 degrees. This is because if it is to warm it will allow bacteria to grow, too cold and the brining reaction time will be slowed down too much.
- When brining it is important to let it sit for at least 6 hours for smaller pieces and up to 12 hours for larger pieces. If the fillet is fresh or frozen will also play a big role in how long to brine. If the fillet is fresh, it will need more brining time than frozen.
- Once the fillet has finished brining, any excess salt will need to be removed. To do this you need to rinse the fillet in fresh water for at least 20 minutes. This can be done by running the fillet under cold water while sitting in a container. Periodically agitate the salmon to ensure all of the salt has been removed.
- Take care and be gentle with the salmon while agitating it, it is very delicate and can be broken up very easily.
- If you are feeling game, take a thin slice of the salmon fillet at this stage and check for saltiness. If it is too salty let it sit in the fresh water for a further 10 – 15 minutes.
- If raw salmon is not quite your thing, heat in the microwave for a minute before tasting).
- For every 2 quarts of water, use about 2/3 cup each of salt, white sugar and brown sugar, which is enough for up to 4 pounds of salmon.
Cure your Salmon For Cold Smoking
The third step in cold smoking your salmon is the curing process.
- To start evenly spread 1/3 of your cure in a glass baking dish that is slightly larger than your fillet/ fillets. Lay out your salmon pieces (give yourself a buffer between the salmon and the edge by around 1/2 inch).
- Store your remaining cure overtop and make sure there are no gaps and everything is covered completely.
- You are going to want to keep your salmon covered in the refrigerator for at the very least 12 hours, 24 – 48 hours is ideal. You will get a much better result the longer you let the salmon cure for.
- While the salmon is curing it is the perfect time to add additional herbs or spices. This will give the salmon a more in depth flavor and also a more interesting appearance.
- Over the curing period, the salt that remains in the salmon will evenly distribute throughout the fillet. This will stop the fillet from having a salty centre.
- At this stage the proteins in the salmon will start to bind together, this will start to dehydrate the salmon. Which makes the salmon perfect for adding to the smoker.
The Pellicle Formation Starts
If you complete the steps above you will find that the pellicle now starts to form.
The pellicle is a very thin layer of dry proteins that were liquified during the brining process. You can tell when the pellicle layer has been formed because you will see a glossy, clear coating over the entire fillet.
The pellicle is essential because it stops large amounts of liquid from escaping from the salmon as it smokes.
Charlies Hot Tip
Not only do I love cold smoked salmon, I also love hot smoked salmon! I find that due to flavour you need for smoked salmon, you need to make sure you are not leaking ANY smoke!
Cold Smoke Your Salmon Fillets
Finally, we are ready for the smoking!
Remove your salmon from the refrigerator and wash off any excess cure.
When smoking it’s important to have a good amount of space around each fillet. This will ensure that there is good smoke circulation and all pieces are smoked evenly. Also try to have each piece of the salmon evenly spaced from the front, back and sides.
Depending on the size and the number of fillets in the smoker, the actual smoking process should take around 10 – 20 hours. Keeping in mind larger/ thicker pieces will take longer than smaller pieces. If the smoker has more inside of, it will also take longer to smoke.
During the smoking process, the fillet will become more firm and look drier. The longer the fillet is smoked for the more intense the smoke flavor will be.
Once smoked the salmon is smoked I like to eat it right away. However, the best way to store it (if you can wait that long to eat it) is to vacuum seal it. It will last for several months unopened. Or if you would prefer to freeze it will last for up to 1 year.
