How to make
Mix the yeast, sugar, a little cool milk and a little flour. Cover the leaven with a towel and leave in a warm place until doubled in volume. Pour in the effervescent yeast in a well in the middle of the sifted flour.
Knead a smooth and elastic dough along with the other products, and if necessary, add a little more flour. Cover the dough with a towel and leave it to rise again in a warm place. Fry the chopped onions in heated butter and salt them at the end. Spread the dough out into a thin sheet.
Distribute the onions, sprinkle with a little oregano and crumbled cow's cheese. Roll up the sheet and twist it. Put it twisted and wrapped in a greased baking tin.
Brush it with a beaten egg and put the twisted onion pie to bake in a pre-heated 360°F (180 °C) oven.
