SMOKING SALMON FISH

The 3 Men's Fish Smoking Process

The following process is for smoke cooking (sometimes, called hot smoking) as opposed to cold smoking. Smoke cooking is in effect a cooking process. Use this technique for fish that you expect to eat immediately or within up to three weeks of cooking (six weeks if the finished product is vacuum sealed).
This process can be used for any type of fish and involves preparing the fish, brining, drying and smoking. It is easiest to work with filets of fish but you can also use fish steaks or cleaned whole fish.
For pictures of this entire process check out   'The 3 Men Fish Smokery'



Use only fresh fish or fish that was frozen immediately after catching and thawed just before cooking. Rinse in fresh water and trim all loose pieces and bones. Hemostats work well for removing bones in filets of fish. Your finished product will be much more attractive if you clean and trim the fish properly. Skin may be left on or removed. It is easiest to leave the skin on for the smoking process since with most fish it can be easily removed after smoking. It is best to work with batches of fish that are similar is weight as this is one of the variables in establishing the time of brining.
  • 1 U.S. gallon of water at room temperature
  • 2 cups salt
  • 1 cup brown sugar
  • 1/3 cup lemon juice
  • 1 tablespoon garlic juice (or 1 tablespoon garlic powder)
  • 1 tablespoon onion powder
  • 1 tablespoon allspice (it is best to sift this into the water to avoid clumping
  • 2 teaspoons white pepper

*This recipe is for an 80º brine and can be multiplied as many times as needed
In a glass, plastic or ceramic container (never wood or metal), mix all of the ingredients thoroughly until dissolved. A small handblender such as those made by Braun works well for mixing the ingredients. For brining fish we like to use rectangular plastic containers that are four inches to six inches deep. These can be purchased at restaurant supply stores. As long as it is not wood or metal, any type of container is acceptable.
Place the fish in the brine solution ensuring that all pieces are completely submerged. Place plates on top of the fish to maintain complete submersion. For short brining periods (three hours of less) in cool temperatures the brine may be at room temperature if the fish is well chilled before placing it in to the brine. If the fish is not well chilled and/or the ambient temperature is warm, place the brine and fish in a refrigerator for the duration of the time of brining. Alternatively, you may place bags containing ice in to the brine mixture to cool the temperature.

The type of fish, the weight of the pieces and whether the skin has been left on or removed establish the brining time. Following are general guidelines for time of brining. Adjustments to the general guidelines for type of fish and whether the skin is left on or removed are discussed below.

Weight of Each Piece of Fish
Time for Brining
Under ¼ lb.
30 minutes
¼ lb. To ½ lb.
45 minutes
½ lb. To 1 lb.
1 hour
1 lb. To 2 lb.
2 hours
2 lbs. To 3 lbs.
3 hours
3 lbs. To 4 lbs.
4 hours
4 lbs. To 5 lbs.
5 hours

Note that the total weight of the fish is irrelevant. Time of brining is established by the weight of the individual pieces of fish. That is why it is easiest to work with batches of fish of similar weight.

Adjustments to Time of Brining - If the skin is left on the fish then increase the time of brining by 25%. For oily fish (Great Lakes chub, Atlantic herring, Gulf pompano, most trout, whitefish, cod, mackerel, salmon, sturgeon, dogfish, etc.) increase time of brining by 25%.
Overhauling - To obtain the best curative and flavoring effect from brining, all pieces of the fish must be freely exposed to the brine solution. Overhauling is simply the process of rearranging the pieces of fish in the brining container to provide for a proper turnover. Overhauling is not necessary for brining periods of two hours or less. For longer periods overhaul occasionally (e.g., for a four hour time of brining you might overhaul once half way through the time of brining).

At the end of the brining period the fish is removed from the brine for drying. The 3 Men are not all in agreement as to whether or not the fish should be rinsed in water after removing it from the brine. If rinsed it should be lightly rinsed in fresh water. If you do not rinse the fish the finished product will be somewhat saltier than if you rinsed it.
After removing the fish from the brine, place the fish on elevated racks for drying prior to smoking. It is easiest to use the same racks that you will use in your smoker. Lightly oil the racks (a product like Pam works well for this) to avoid sticking. Place the racks of fish in a cool breezy place protected from flying insects. We usually place an electric fan near the racks to provide a breeze. The time for drying is usually one hour at which time a thin glaze called the pellicle is formed on the fish. The pellicle aids in the development of the color and flavor as the fish is smoking. It also helps keep in the juices and retain the firm texture of the fish as it is smoked.

Fish smoking can be accomplished in many different types of smoking equipment. Follow the manufacturer’s instructions. Depending on the type of equipment you are using, you will use wood chips or chunks, sawdust, pellets or whole logs for your source of smoke. We have found that any hard wood works fine for smoking fish. We have used alder, apple, oak, hickory, pecan, cherry, mesquite and grape stock with excellent results.
We use Cookshack electric smokers, Weber bullet smokers, Weber kettles and very large smokers like the types manufactured by Pitts & Spits and Jerry ("J R") Roach. Any type of smoker will work as long as there is a source of smoke and a source of heat at a consistent temperature. We generally smoke our fish at approximately 190 degrees. Lower temperatures can be used with a corresponding adjustment to the smoking time. At 190 degrees we generally follow these approximate smoking times:

Weight of Each Piece of Fish
Approximate Smoking Time
¼ lb. To ½ lb.
1 and ¼ hour to 1 and ½ hour
½ lb. To 1 lb.
1 and ½ hour to 2 hours
1 lb. To 2 lbs.
2 hours to 2 and ½ hour
3 lbs. To 4 lbs.
2 and ½ hour to 3 hours

The foregoing represents approximate smoking times which will vary based upon the type of fish your are smoking, the equipment you are using and the temperature at which you are smoking. Additionally, the cooking time needs to be increased depending on how many times you lift the lid or open the door to check on progress.
Smoked fish is done when it flakes easily while pressing it lightly with a knife of fork. On larger pieces of fish you may want to test for doneness with an instant-read thermometer. Fish is done when the internal temperature reaches 140 degrees.
When you are done smoking the fish, remove the racks to an elevated surface to cool. We sometimes set the racks on top of beer cans, as usually there are plenty of those around. Once the fish has cooled for approximately one-half hour, wrap tightly in foil and place the foil parcel in a zip lock type bag or (preferably) vacuum seal in plastic pouches.

Water for Brining – We usually use bottled water for brining.
Salt for Brining – Some prefer kosher salt for brining but most recently we have used regular table salt (not iodized) which can be purchased inexpensively in large quantities at the Price Club or Smart & Final.
Quantity of Wood for Smoking – Don’t do as we have done and figure that if a little smoke is good then more must be better. Too much smoke will cause the fish to taste bitter. Use just enough wood to maintain a steady smoke.
Keep Notes – Get a binder and record as much information as you can about your brine, brining time, smoking time, etc. This way you can experiment and refer to your notes at a later date.
Vacuum Sealing – We like to vacuum seal our finished product as it extends the shelf live by about 50%. It also makes for an impressive and appealing finished product. We use Vacmaster and FoodSaver vacuum sealers.

Here are some good books that provide information about smoking fish:

TUDO SOBRE DEFUMAÇÃO DE PEIXES

Smoking is one of the oldest methods of preserving fish, or any other meats for that matter. Long before there were refrigerators and freezers, our fishing ancestors learned to use a combination of salt and smoke to keep fish from spoiling. Today, smoking is no longer "necessary," but it remains popular for the flavor it gives to such fish as salmon, tuna, trout, sturgeon, bluefish, and sablefish.

Smoking methods vary, but all are based on a few common principles. First, the fish is treated with salt, either in the form of a strong brine or a surface coating of dry salt. During this curing stage (which can last for anywhere from a few minutes to many hours depending on the size and density of the fish), a two-way exchange takes place, with much of the moisture drawn out of the fish and some salt soaking in. This combination of reduced moisture and salt inhibits the growth of spoilage bacteria, a basic principle of all cured meats.

Most fish are given a second cure after the initial salting to add additional flavors. Recipes for this second cure are often proprietary secrets, but they typically include sugar in some form; like salt, sugar both draws moisture out of and soaks into the fish. Often the second cure will include spices or herbs, and sometimes a bit of rum or whisky.

After curing, the fish is rinsed to remove the salt and other curing ingredients from the surface, then allowed to dry in cool flowing air until a shiny, slightly tacky skin (pellicle) forms on the surface. The pellicle serves several functions: it provides an ideal surface for the smoke flavor to adhere, it helps seal in the remaining moisture through the smoking process, and it prevents the fats in the fish from rising to the surface and spoiling.

The actual smoking takes place inside a chamber filled with smoke from smoldering hardwood. At this point the process diverges; fish are either "hot-smoked" or "cold-smoked," depending on the temperature of the smoking chamber. The choice determines the texture, flavor, and potential uses of the fish.

In cold-smoking, the fish is slowly smoked, often for 24 hours or more, at a temperature from 60 to 110 degrees F. Commercial smokers use a system of liquid-filled cooling tubes, a sort of reverse radiator, to remove excess heat inside the smoking chamber. In this temperature range, the fish is not cooked, just dried a little further and infused with smoke flavor, so it remains especially moist and tender.

The best known cold-smoked fish is the type of smoked salmon variously known as "lox" or "Nova." Lightly cured, tender, and moist, it can be sliced thin without breaking apart. (The name Nova, by the way, dates from an earlier time when much of the salmon in New York came from Nova Scotia; today, the fish is likely to be either Pacific Chinook or coho salmon or Atlantic salmon raised on farms.) Sturgeon also takes beautifully to the cold-smoke treatment.

Hot-smoked fish actually cooks during the smoking process, in which the smoke gradually reaches a temperature of up to 180 degrees F. Smoking time is generally less than for cold-smoking. The result is firmer and flakier than cold-smoked fish, yet moister than grilled or "barbecued" fish. Temperature control is just as critical in hot-smoking; if the heat gets too high, the fish will lose all its moisture before the smoking is complete. This is the kind of smoked fish produced by most home-sized smokers.

Many types of fish can be hot-smoked. In addition to salmon, commercially available choices include trout, various tunas, and the Northwestern fish properly known as sablefish but usually marketed as "black cod." The golden-colored whole smoked whitefish sold in delis also fall into this category, as do smoked mackerel and bluefish.

Don't expect to slice hot-smoked fish the way you can lox; it will crumble if cut too thin. Cut hot-smoked fish into cubes, chunks, or thick slices, or just flake it apart along the natural seams between the muscles. In this form, the fish is ready to use in salads and other cold dishes, or gently warmed in a pasta sauce.

Ideally, smoked fish should get its flavor and mahogany color from the smoke, but many cheaper smoked fish have smoke flavor added, and some varieties, like some hot-smoked and garishly colored "kippered" salmon, use artificial food color as well. In fact, some of the brightly-colored cured fish sold in supermarkets are not smoked at all, simply flavored with a cure that includes smoke flavoring.

In pre-refrigeration days, smoked fish were heavily cured and smoked fairly dry, for storage at room temperature or in a cellar. Today's cures are lighter, so most forms need to be refrigerated. They will last longer than fresh fish, but you should still plan to use them within a couple of days of purchase. Both hot-and cold-smoked fish can be frozen, and in fact a lot of delicatessen lox is stored and shipped in this form.

For longer storage, some smokers pack their fish in cans, or in the newer vacuum-sealed foil packaging known as a retort pouch. The latter is like "canned fish without the can"; just like canned fish, the fish in a retort pouch has been fully cooked and sterilized in the packing process, so it can be stored at room temperature for up to seven years. Don't confuse retort pouches with vacuum-packed plastic packages, however; vacuum-packed product is just as perishable as lox bought from a deli. Read and follow package labels carefully with these as with any seafood product.

Lox-and-bagel is a common weekend brunch combination, but here's another variation on the same theme that's just as suitable for lunch or supper. It's based as much on the Danish open-face sandwiches known as smørrebrød as on the Jewish deli standard.
