Beat egg yolks into the chocolate mixture, beating each well, then stir in flour.

In a clean, greasefree bowl, beat egg whiltes slowly until they are frothy. Increase the speed, add salt, and continue beating until soft peaks form. Sprinkle over the reserved sugar and beat until the whites are stiff and glossy. Beat one-third of the whites into the chocolate mixture, then fold in the remaining whites.
