Chop a handful of parsley and mix it in a stewpan with two ounces of butter, two ounces of flour, pepper and salt; moisten with half a pint of water and a table-spoonful of vinegar. Stir the parsley-sauce on the fire till it boils, and then pour it over the fish, drained free from water, on its dish.
