Prepare the filling: Pull open the dates and and release the pits by hand.

Transfer the dates to a food processor and add the ghee, orange blossom water and mastic gum, blend to get a paste. If your food processor is having a hard time making the chunks smaller and smooth, add a couple of tablespoons of water to the mix.

Prepare the dough: in a large bowl, place the farina, semolina, flour, ghee, powdered sugar, milk powder, baking soda and rose water.

Mix the dough with the tips of your hands, the mixture would first crumble, continue kneading until you have a smooth malleable dough. Divide it into two equal portions.

Lightly grease a 40 cm / 15 inches round oven pan with a tablespoon of ghee, and with the palm of your hands, spread one of the dough evenly over the greased cake pan, fully covering it.

Evenly spread the date filling (if the date filling is still stiff add 1 or 2 tablespoons of orange blossom water to make the date more malleable and easy to spread, but don’t go heavy), the date equally should cover the dough.

Top it with the other half of the dough. Divide the dough into pieces and spread it over the filling one piece at a time, patching it together with your wet palm, level the patches forming a smooth connected surface.
