Put two onions, a carrot, and turnip, cut in slices, into a stewpan, or very small fish-kettle, with a good bouquet of parsley, a few sprigs of thyme, one bay-leaf, six cloves, a blade of mace, a little salt and pepper, and two glasses of sherry; lay your tench over (it will require four for a dish, and they may be either cooked whole, or each one cut into two or three pieces), add a pint of water, cover down close, and stew rather gently over a slow fire for about half an hour; take them out, drain upon a cloth, dress upon a dish without a napkin, and pour a sauce over, made as directed for sauce matelote, cream sauce, or Beyrout.
