In a deep bowl, beat eggs, salt, yeast and nigella very well.
Add all the flour at once.
Gradually add water while continuing to knead until you get a dough similar to pizza dough or slightly softer.
Leave the dough to rest for 10 minutes.
Add the oil and knead it again for 5 minutes continuously.
Cut the dough and shape it into medium-sized balls (about 25).
Cover the dough circles with plastic wrap and leave in a warm place until fermentation (for half an hour).
Take a medium-sized plate, grease it with a little ghee and sprinkle it with flour.
Roll out each ball of dough all over the tray
Grease the dough after rolling it out with butter after heating it, provided that the butter covers the entire layer.
Roll another ball on top of the butter and repeat with all the balls you have until you have a multi-layered pie.
After greasing the last layer with butter on the face, pour milk on it, then sprinkle a little nigella.
Heat the oven to 200 °C degrees/400 °F
Put the tray in the oven until the pie is puffed and turns golden, for 30 to 35 minutes
Serve and enjoy your Bint Al Sahn!
