Mash the butter; add piquant mustard, cognac, salt, and mix.

Cut away the crisps of the white round bread. Cut the bread along into two parts.

Spread the butter mass on the lower part of the bread, put some salted salmon slices on it, cover it with the second part and coat it with cheese mass.

To make cheese mass mix cottage cheese with cream cheese, add chopped onions (leave some circles of onion for decoration), salt and red ground pepper.

Divide the cake into 12 segments-servings. Decorate each serving with a slice of salted salmon, an onion circle, slices of garden radish and pickled cucumbers.
