Blanch eighteen oysters to boiling-point in their own water; drain, and return them to the saucepan, moistening with half a pint of good Allemande (No. 210); season with half a pinch of salt. Make a plain omelet with twelve eggs as for No. 450, bring the sides toward the centre, and fill it with the oyster preparation. Turn it on a hot dish, pour the rest of the sauce around, and serve very hot.
