Checkpoints:
1 How do I know it is firm peak: Check the tip of the egg white. The hook should be curve downward
2 Make sure the cake batter is runny or it will hard to bake it evenly
3 If the cake cracks while baking, the oven temperature maybe too high. If it rises up too quick, open the oven door to lower the oven temperature.
4 If the cake crack while rolling up, the cake maybe too cold. Roll it up when the cake still warm.
