How To Defrost Frozen Salmon?
You can refer to the following 3 ways to choose a suitable and safe defrosting method for yourself.
Method 1: Defrost salmon in the refrigerator
With this method, you need to take the fish from the freezer to the outside environment about 12 hours before processing. The time may be longer if the volume of salmon is larger, for example, fish weighing 450 – 700g should be taken out 24 hours before.
Remove the bag or packaging containing the fish, use foil or food wrap to wrap tightly around the fish to prevent bacteria from contacting the surface of the fish and multiplying, which will cause rancidity.
Put the fish in a bowl and place it in the refrigerator at a temperature of 2 – 5 degrees Celsius. Be sure to keep the fish away from other foods in the refrigerator so that they will smell.
You observe until the fish is soft, then take it out and process it.
Method 2: Defrost salmon with cold water
With this method, you need to take the fish out of the freezer for about 30 minutes before processing. The larger the weight of the fish, the more time it takes.
As with the method above, you need to empty the bag or container of salmon. Wrap the fish with paper or plastic wrap to prevent bacteria from multiplying.
Then soak the fish in a bowl, basin, or soak it directly inside the sink. About 30 minutes, you proceed to change the soaking water once.
Finally, wait until you feel the fish becomes softer than it can be processed.
Method 3: Defrost salmon in the microwave
The first thing you need to do is take the fish out of the freezer and remove all the packaging, bags, or boxes of fish.
Wrap the fish with tissue paper, then place the fish in a glass dish. Note that the plate must be large enough so that the piece of fish does not come out and the fish fits in the center of the plate.
Put the fish in the microwave and turn on the defrost mode on the microwave for 4-5 minutes. For fish weighing about 450 – 500g, the capacity used is about 30%. You can adjust accordingly based on the weight of the fish.
After about 2 minutes, turn off the oven, then carefully flip the fish. Gloves can be used to avoid burns. Then continue to place the salmon in the oven until the rest of the time is up.
Finally, take the fish out and leave it out in the kitchen until the fish is soft, then proceed to process immediately!
Notes when defrosting salmon
- You should not defrost fish with warm or hot water to avoid the condition that the fish is not completely defrosted and does not give bacteria a chance to grow.
- Salmon after being defrosted needs to be processed immediately to avoid affecting the taste of the fish and to avoid fish contamination.
- Never refreeze fish that have been defrosted. Because home conditions cannot be as standard as frozen facilities, this is one of the reasons why fish meat is rotten and tender even after you re-freeze it.
- You need to consider the amount of salmon that needs to be defrosted so that it is enough to avoid waste and is safe for health.
- With the thawing of the whole salmon, at the end of the process, you should check to see if there are any ice cubes inside the fish’s belly. If there is still ice, you can bring the fish to flush with clean water so that the ice falls out and you can go to the kitchen to process it.
- For safekeeping, it’s a good idea to record or mark the packing date before you store it in the freezer. And you should only use fish that has been frozen for no more than 8 weeks by the time you defrost and use it.
How to Prepare The Whole Salmon
First, use a scalpel to cut the fish’s belly, cut and remove all the intestines inside the fish’s belly.
Then you use a very sharp knife and then cut down the direction from the head to the tail of the fish. You should control the knife to follow the fish’s backbone to get all the meat, avoid wasting it. You should also cut evenly and gently so that the cut is smooth to help the fish meat evenly and without interruption.
After that, clean the scales on the outside of the fish. Place the fish on a large cutting board or a clean, dry flat surface. This will help keep the fish from slipping, the fish will not move and have a large space for you to work easily.
After cutting off one side of the fish, you use one hand to stretch the fish skin, the other hand uses a very sharp knife to cut the skin off. You cut from the tail of the fish to the belly of the fish, it will be easier to manipulate.
Finally, use tweezers to pick up all the bones that are still in the meat. Now you can cut the fish into large and small pieces depending on the taste of the dish you are about to prepare.
In fact, if you’re cooking at home, you should buy pre-filled salmon. They are sold a lot in markets and supermarkets and other e-commerce sites to be safer and save more time. Pre-processing whole salmon is more suitable for restaurants or parties with large servings.
