Separate egg-yolks and mix well with baking powder, cooking oil and yogurt. Add flour gradually while stirring the mix. Pour the dough in a plastic bag and leave for 1-2 hours.
Peel and ground almonds. Mix well with sugar and cardamom powder. Spread some flour on a table-top. Make orange-sized balls from the dough. Flatten the ball on the table-top to a thickness of 0.5 cm using a roller.
Cut circles into the dough with a cup. Place some of the almond-sugar mix at the center of each circle. Bring the edges of the circle together and press to close completely.
Fry in pre-heated oil until colour changes. Drain the excess oil, then roll in fine sugar.
