To prepare the salmon use a sharp knife, slice under the skin from the thin end back to thick end of the salmon, leaving the skin intact 2 cm from the end. Roll up the salmon from the thin end inwards, leaving a pocket, wrap the skin around the outside and secure the rolled salmon with kitchen string. Repeat for the remaining fillets.
