Step 1

If you have a very large cod fillet, you can first cut it into 2 or several pieces. It's easiest to do so with scissors.

Step 2

Carefully rinse the fish with fresh water. Make sure you cover it with water.Repeat this procedure 2-3 times if you feel like there’s too much salt left.

Step 3

Soak the fish in some more fresh water and keep it in the fridge for 12-24 hours, in an airtight container. Make sure to change the water every few hours.

Step 4

Either cook the whole piece once you've soaked it long enough or take a small piece and boil it and then taste it. If it's too salty, just keep soaking the fish for a few more hours before cooking the whole fish.

Step 5

Once you've soaked the fish, rinse off any excess salt.

Step 6

Place the cod in a pot with lots of water. Add a squeeze of lemon, if using.

Step 7

Bring it to a gentle boil and cook for about 10-12 minutes. Don’t boil it vigorously, though, because the fish could become tough and rubbery.

Step 8

Skim off any foam that's formed on top.

Step 9

Once cooked, remove the fish bones using a fork and a spoon.

Step 10

Refrigerate any leftovers. It can be stored in the fridge for about 3 days.When the cooked fish has cooled completely, you can put it in a freezer bag and freeze it for about 2 months. To thaw, just put it in the refrigerator overnight. Once it has thawed, do not refreeze it.
