How to cook
Pour the flour into an oven dish. Make a well. Pour the yoghurt and baking soda in it, leave it to bubble.
And most of the grated feta cheese to them. Knead a soft dough, make balls from it about the size of a meatball.
Arrange them in a greased tray with some space in between them. Make an indentation on top with your finger, put a lump of butter or margarine and it.
Sprinkle the remaining feta cheese or cheese on top - whatever you like. Bake in a hot oven.
