...and finish with the last layer of pastry. Your first millefeuille is now ready. Assemble all the others in the same way.
Serve without delay (see below).
Remarks
It is always difficult to eat a millefeuille tidily. It tends to resist being cut with a spoon but, as this one has very thin pastry, cutting it is much easier.
Millefeuilles do not keep well, as the cream ends up making the pastry soggy. They should be assembled at the last minute and eaten as soon as possible.
