Flip it up after about 1 minute with a wooden spatula and fry the other side about 1 minute. Take it on a plate and oil the pan again and repeat the same steps. Don’t forget to put 1 tsp oil in the pan each time.

Fill them with various jams and roll them up.

Optionally, you can slightly dust them with powdered sugar.
