I apologize again for the fact that there is no photo for each step. I did it all on the birthday of his mother, managed to photograph only the final result. So let's start to cook: Cakes ready-made "Napoleon" spread liberally with mayonnaise. Onions finely cut and fry in vegetable oil until Golden brown. Canned open and take out the fish, pre-drain the juice.Mash with a fork.Egg grate on a coarse grater. Divide the onion into 2 parts, one adding pink salmon, the other the egg.On a greased mayonnaise cake put 1 cake layer onion, egg, 2 layer pink bow. do this until we run out of cakes. The last top layer and sides, spread it with mayonnaise before it crushing the cake that the layers are well glued together.
