Walnut cream:
In a saucepan put the water and the sugar minus two spoonfuls, make a syrup at the point of ball 120ºC.
Beat the egg white with the salt and the tartar cremor. When it foams a little, add the sugar little by little and keep beating.
When the syrup reaches this temperature, add the meringue in the form of a thread and continue beating until it is cold.
Gradually add the butter in cubes at room temperature. It is integrated until it is creamy.
Carefully add the ground nuts. Transfer the cream to a piping bag with a curly mouthpiece. Keep it in the fridge.
Once the sponge cake has cooled, cut it in half and cut it horizontally. It is filled with part of the cream. Cover with the other layer of sponge cake and finish the rest of the cream as you like. Powdered cocoa is sprinkled.
