Cream one fourth cup of butter, and beat into it the yolk, then the white of an egg. Add, also, two tablespoonfuls of sugar and one fourth teaspoonful, each, of mustard, salt, and paprika. Then pour on very gradually, beating constantly, half a cup of hot vinegar. Cook over hot water, until the mixture thickens a little - it should be like thick cream - and let cool before stirring into a generous pint of fine-shredded cabbage, prepared for salad. This makes an acid dressing.

Beat the yolks of three eggs, half a teaspoonful of mustard mixed for the table, two tablespoonfuls of sugar, and one fourth teaspoonful of salt. Add two tablespoonfuls of butter, then, gradually, five tablespoonfuls of hot vinegar. Stir and cook over hot water until the mixture is thick and smooth. Just before using, mix with crisp, fine-shredded cabbage. The centre of a handsome head of cabbage may be cut out and shredded and the shell thus formed used as a bowl from which the salad is served. The cabbage bowl may stand upon a hot napkin holding hot fried oysters. If the cabbage bowl be chilled, the heat of the napkin will not reach the salad.
