Place the flour in the form of a volcano on a marble table.
Put the eggs in the centre and add butter (previously melted), a pinch of slat, sugar, lemon rind and water.
Mix it well until the mixture is even and then wrap it around the baking trays. When the oil is hot, fry the mixture. Remove from the baking tray and put it on paper to absorb the excess oil.
To make the cream, boil the milk with vanilla and lemon rind.
In a bowl, beat the egg yokes with corn flour, sugar and a drop of cold milk. This mixture is added to the milk, boiling and stirring non-stop until it gains consistency. Add a drop of cognac and cook for a few more minutes.
Fill the wafers with the cream and sprinkle with icing sugar.
