What specific method is suggested to introduce moisture when preparing very lean cod fillets?

Answer

Wrapping the fillet in parchment paper (en papillote) with lemon and wine

Because cod, especially very lean fillets or previously frozen specimens, has a low natural fat content, there is a risk of the texture becoming dry during cooking. To counteract this, it is important to actively introduce moisture during preparation. One highly recommended technique for baking cod is wrapping the fillet in parchment paper—a method known as en papillote—along with additions like sliced lemon and a splash of wine. This method effectively traps steam generated by the added liquids, thereby keeping the protein supple and moist. This contrasts with richer fish, such as salmon, which often do not necessitate such focused moisture introduction.
