Now the same way should be repeated with the second layer of cake: a layer of cream (I leave a little cream to cover the edges of the cake, I put it in a cooking bag and put it in the refrigerator), trout, onion, dill. And again lay out a layer of cookies – this will be the last layer. Squeeze the cookies well. The top of the cake does not need to be smeared with cream. Wrap the pie in plastic wrap and put it in the refrigerator overnight so that it is well soaked.
