To a solid pint of oysters use a dressing made as follows: Beat well two
eggs and add to them half a gill each of cream and vinegar, half
teaspoonful mustard, celery seed, salt each, one-tenth teaspoonful
cayenne, and a tablespoonful of butter. Put all in a double boiler and
cook until it all is as thick as soft custard (about six minutes),
stirring constantly. Take from the fire. Heat the oysters in their own
liquor to a boiling point then drain and add the dressing, mixing
lightly. Set away in cold place until needed.
