Soak ackawi cheese in water for at least 6 hours to remove saltiness.
Mix ground kanafeh dough with margarine and 3 tablespoons of melted sweet butter.
Add 2 teaspoons of powdered orange dye to 2 1/2 tablespoons of butter and spread out into a large pan. Spread out kanafeh dough mixture into a pan, on top of the butter, and press it flat.
Grind ackawi cheese, sweet white cheese and mozzarella in a food processor. Layer cheese mixture on top of the kanafeh and bake in the oven until lightly golden and the cheese is melted, about 20 minutes.
Pour simple syrup over the kanafeh and top with pistachios. Serve immediately and enjoy!
