How to make
Put the baking soda and baking powder in the yoghurt to bubble, then mix this with the eggs, oil and flour. Stir to a homogeneous mixture without any lumps. Separately, crumble the feta cheese.
Take 1 phyllo pastry sheet, smear it with a little butter or oil using a brush, place the 2nd sheet on top, smear with 3-4 tbsp of the mixture. Sprinkle with the crumbled feta cheese. Wrap it into a roll starting from the short side.
Arrange the 1st roll in a spiral in the middle of the oven dish, which you've smeared with oil or butter beforehand. The oven dish should be about 11 3/4″ (30 cm) in diameter.
Repeat with the rest of the phyllo pastry sheets and wrap them around the one in the center. If you have any mixture left over, smear it on the phyllo pastry on top.
Bake in a preheated 360°F (180 °C) oven for about 40-45 min.
After you take it out, sprinkle with a little water and cover it for about 10-15 min.
Enjoy this fabulous phyllo pastry!
