Method
Generously brush a large non-stick frying pan with a portion of the melted butter.
Layer 8 baklava sheets one by one, brushing melted butter between every single layer.
Whisk the milk and eggs in a bowl to create the soaking liquid.
Tear one daily yufka into pieces, soak them in the milk-egg sauce, and spread them over the baklava base.
Spread the mixed kashar and çeçil cheese evenly over the soaked yufka.
Soak the second daily yufka in the sauce and place it over the cheese layer.
Layer the remaining 8 baklava sheets, buttering each one. Fold in the overhanging edges at the 6th layer and tuck everything in neatly.
Brush the top with more butter and carefully slice the raw börek into squares while still in the pan.
Cook on the stove over the lowest heat setting . Flip using a plate once the bottom is golden, and fry the other side until crispy.
Notes
Use a combination of Kashar and string cheese to get that legendary stretchy texture. To keep the bottom from burning while the cheese melts, cook over low-medium heat and cover the pan with a lid for the first few minutes to trap the steam.
