FILLETS OF MACKEREL WITH RAVIGOTE SAUCE
Cook the fillets of four fish in a buttered dish with salt, pepper, grated nutmeg, and half a cupful of white wine. For the sauce chop fine four shallots and put into a saucepan with two tablespoonfuls of butter and four tablespoonfuls of tarragon vinegar. Reduce half by boiling and add a pint of white stock thickened with a tablespoonful each of butter and flour cooked together. Add two tablespoonfuls of butter, pour over the fish, and serve.
