Step 1

Wash and dry the fillet of cod. Mix together the salt and sugar

Step 2

Sprinkle half of the salt and sugar into a baking tray and lay the fish on top

Step 3

Cover with the remaining salt and sugar and pack tightly

Step 4

Cover with cling film and refrigerate for 24 hours. If the cod fillet is particularly thick it will need longer

Once the cod has firmed up rinse well in cold water and pat dry

Step 6

Wrap in muslin cloth and leave on a wire rack in the fridge for 7–10 days

Step 7

The salt cod will keep in the fridge for a couple of weeks or the freezer for a few months. It needs to be soaked in cold water for 24 hours before using, changing the water at least twice during this time
