Remove the skillet from the heat and add the butter and capers. Once the butter melts and begins to smell nutty, about 2 minutes, transfer the fish to serving plates. Squeeze the lemon into the skillet, add the parsley, and stir briefly. Spoon the butter-caper sauce over the fish and serve.
Cleaning
Serve promptly and use a paper towel to immediately remove butter-caper sauce residue from the skillet. (Be careful! The pan will still be hot.) When pan has cooled enough to handle, rinse well, wash with a firm cleaning brush, dry thoroughly, and apply a dab of Field Seasoning Oil.
