I started using shredded mozzarella. I soak the shredded mozzarella in some cold water and replace the water every 5 minutes for about 15-30 minutes. (depending on how much cheese i have) This takes the salt out but does not make the cheese sweet. When you dip the qatayif in the qatar (sugar water mix) it gives enough sweetness. Plus side to using mozzarella: Its way cheaper and way easier to get in stores. (I think healthier too)
Another tip: I broil my qatayif in the broiler for like 3-5 minutes and flip them for like a minute. (I first coat the pan with oil and rub some oil on the pieces as well) Much healthier than frying.
This is my 1st post on this board and I hope some of you ladies find this useful inshAllah. ;)
