Boned baked pickerel

Have your fishmonger take out the backbone when he has split the fish lengthwise, also have him extract every other bone he can get out without tearing the flesh too much. Marinade for an hour in a bath of olive oil and lemon juice. Cover the grating of your bakepan with thin shavings of salt pork, lay the fish upon this, skin-side downward, wash with melted butter, bake, covered, half an hour, baste and cook ten minutes more. Serve with Hollandaise sauce.
