Preheat the oven to 170 degrees C (340 F).
Butter a 24cm (9.4 inch) round baking tin.
Mix the flour with the soft butter, sugar, and yolks until you get a homogeneous dough.
Give the dough a round shape and place it in the prepared pan.
Press gently and smooth it out so that the bottom of the tray is well covered.
Chill the dough while you prepare the filling.
Separate the yolks from the whites.
Over the yolks put the flour, grahams, and cream and homogenize.
Mix well then add the seeds from the vanilla pod and the grated lemon rind.
Beat the egg whites well with a pinch of salt until you get a firm froth.
Add the sugar one spoon at a time and continue mixing.
Place the meringue over the cream and mix gently with upward movements.
After homogenizing the filling, pour it over the crust and level.
Bake the pastry for 40-50 minutes on medium heat until it puffs up slightly and browns on the surface.
When cooked, turn off the oven but leave the bread in the oven for 2 hours to cool gradually.
Then put it in the fridge for a few hours.
To serve, dust with sugar. It is a delicious pastry, enjoy!
My source of inspiration for this wonderful pastry was Bucataria Nainei.
Thank you so much!
