Cook carrots and onions slowly in 1 T butter. When tender, add 1 T butter, salt, pepper, parsley, and fish fillets. Add wine, bring to a boil, and cook slowly for 12 minutes. Remove fish to serving dish. Cook liquid until reduced to 1/2 original quantity and thicken by creaming together remaining 1 T butter with flour. Bring to a boil, moving pan around instead of stirring mixture to combine it. Pour over fish. From "Pirate's Pantry" formatted by Mary Dishongh Bowles.
