Wipe the empty side of the pan with oil-soaked kitchen paper and pour another 1/3 of the egg mixture into the empty space of the pan.
Lift the folded egg up to let the egg mixture run under it.
Fold and roll the egg from one side of the pan and wipe the empty space of the pan with the oil-soaked kitchen paper.
