The dough I made the day before cooking. It's simple - cheese, 1 egg, butter, baking soda, salt (1 tsp) and flour mix to the consistency of elastic dough does not stick and put it in the refrigerator. Onion (next day) cut into squares and cook in a pan under a lid until creamy on low heat (about 40-50 minutes, watching so as not to overheat). At the end add salt and garlic pepper

To the onions add the finely grated cheese and protein (the yolk to leave)

Part of the test to distribute on the form, put the stuffing

From the balance of dough to make the lattice, lay it on the pie and brush the top with egg yolk

Bake at 180-200 deg to Browning the top (about 1 hour, not exactly say). Help yourself! The aroma is awesome!
