Stir nice to get a nice homogeneous. Take the filling and put in the narrower end of sheet and wound two sheets at once roll. Initiate rolls in a buttered baking dish. Gently brush the top with oil. Put the banitsa to bake in a preheated 180 C oven until brown. Remove from oven and pour the cold syrup. * My pan proved narrow and therefore need to cut the part of the peel. From the cut part made triangular banitsi. After firing of the triangular banitsi, can put them in a box without being syrupy and store them in the refrigerator for an appropriate case, then removing them and make their syrup that while hot seasoning the banitsi. * In this way, I do baklava 10 days before the New Year and on the very day it only syrup.
