And now the “trick”, the most interesting. Smear the cakes with herring cream and “glue” the loaf back. Wrap the roll in plastic wrap and refrigerate for 2 hours. Well, all of you! Cut the finished “terrine” along the loaf. Brush the remaining piece of herring with cream. Complete the gastronomic picture with grated yolk, half of protein, green onions and red caviar. Bon appetit to you and your loved ones!
