Separate egg yolks from egg whites.
Add sugar to the egg whites and whip to make meringue.
Mix milk and cake flour into the egg yolks.
Fold the meringue gently into the yolk batter.
Grease a pan lightly and pour in the batter over low heat.
Cover with a lid and cook slowly.
When one side is cooked, flip, cover again, and cook the other side.
Serve the finished soufflé on a plate.
