Oysters put on to boil in their own liquor. Turn them while boiling into a colander to drain. Melt butter in the saucepan, add flour, and stir one minute. Pour in the oyster liquor slowly, which must be not less than a large cupful. Beat the yolks thoroughly with salt, cayenne pepper, and mace. Add to the boiling liquor, but do not let it boil. Put in the oysters, and either use them to fill a pie, the form for which is already baked, for patties for dinner, or serve them on thin slices of buttered toast for breakfast or tea.
