1. To quickly prepare apple rings, first combine flour, salt, yogurt, and egg in a bowl. Mix well to form a thick batter.
2. Peel the apples, remove the core, and fry them for about 10 minutes. Cut into 1 cm thick rings.
3. Heat oil in a frying pan until hot. Then dip the apple rings in the batter and bake in the hot oil.
Turning frequently, when golden brown, remove from the pan, and drain on kitchen paper.
4. Sprinkle with powdered sugar while still warm and serve. Enjoy!
