Thinly spread the baklava sheets; to do that, spread each piece on a marble sprayed with corn flour, sprinkle the obtained paper with corn flour, and repeat the process with sticks several times until you obtain a very delicate paper whose diameter exceeds the diameter of the tray.
Combine the oil with the margarine after heating it a little bit; then take a little bit of it with a piece of cloth and apply it to the tray.
Lay ten sheets of baklava at the bottom of the tray; then spread the hazelnuts on top.
Spread the baklava sheets on the hazelnuts; and on top put the ground almonds, after mixing them with the red coloring.
Repeat the same process again by covering the almonds with ten baklava sheets and spread the pistachios over them, after topping them with pistachio nuts. Then cover with ten baklava sheets
Brush the filo sheets from above with a lot of oil and ghee.
Using a sharp knife, cut the dough in the shape of baklava
Put it in a high-heat oven for about 45 minutes.

Add the farina with continuous and strong stirring; then add in the flour and cook for about 5 additional minutes making sure to stir
Pour one portion of the syrup over the baklava immediately when you take it out of the oven.
