Beat four egg whites with a pinch of salt for 5 minutes. Add sugar and beat the whole mass again into a stiff foam.

Transfer the protein dough into a mold and place in an oven preheated to 120 ℃ for 2.5 hours.

Separate the whites and yolks, add the yolks remaining from 4 whites. Beat the yolks with half the sugar in a separate bowl for 5 minutes. Separately beat the whites with salt, add the remaining half of the sugar. Beat until foamy. Add cocoa and half the flour to the whites, and the remaining flour to the yolks. Mix separately. Add the yolks to the whites, mix thoroughly.
