Fillets of Smelts for Potage à la Duc de Norfolk.—Free the fillets from the bone and mask them thinly over with fish farce (given below); roll them up into a little round form, and fasten each with a little band of buttered paper, place them in a very lightly-buttered stewpan, and put them in the oven to cook for fifteen minutes, with a buttered paper over and a tablespoonful of stock in the pan; take them up, remove the paper, and put them in the basin; reckon one fillet for each person.
