Hurricane cake

This is a Qifeng cake made after the water bath method and I want to test the ordinary baking method that everyone usually makes. But the cake I made today was not very successful. The top of the cake was cracked, unlike yesterday's crack and no opening. Later, I asked a friend who was playing with delicious food and found out that I had forgotten to spray water on the cake. The water was to prevent the skin of the cake from hardening too quickly. After the experiment, many problems were finally clarified. Moreover, the air bubbles in the cake are probably caused by my lack of strength to shake it, so there are holes when baked. I should pay attention to this problem next time.
This time, the three eggs are more and less, but next time, we will have to change it to three egg whites and two egg yolks. We are good children who learn with an open mind. If any master has watched it, please give me advice! And demoulding the bottom is a bit difficult for me. I have already let it cool, but it still touches the bottom, so I took off the cake surface is not very smooth. The funniest thing was that when I took off the tinfoil on the cake, I was too anxious. I rushed to flip the cake upside down and tore off a small piece of cake with the tinfoil. The cake this time is not beautiful, but I am quite satisfied with the internal organization, except for the few holes in it.
I specially made two different methods and found that the water bath method was easier to succeed. But if you play delicious food, you must try any method. I will continue to try this baking method next time, of course, if I forget to spray water on the cake surface!
