252. Trout à la Twickenham.—When you have cleaned your trout, put them into a kettle of boiling water, to which you have added a good handful of salt, and a wineglassful of vinegar; boil gently about twenty minutes, or according to their size, dress upon a napkin, and serve melted butter, into which you have put a tablespoonful of chopped gherkins, two sprigs of chopped parsley, salt and pepper, in a boat.
The remains of trout, salmon, or mackerel are excellent pickled:—put three onions in slices in a stewpan, with two ounces of butter, one turnip, a bouquet of parsley, thyme, and bay-leaf, pass them five minutes over the fire, add a pint of water and a pint of vinegar, two teaspoonfuls of salt and one of pepper, boil until the onions are tender, then strain it through a sieve over the fish; it will keep some time if required, and then do to pickle more fish by boiling over again.
