Chiffon Cake & Me

Chiffon cake and me has come a long way. These are the attempts:

1. Cake was not spongy. It raised. Taste good.
2. Cake still not spongy.
3. Spongy but did not rise well.
4. Cake fell down from tin when it was inverted. It end up in the dustbin.
5. Cracked on the surface and did not rise properly.
6. Deflated after taking out from oven.

I have not given up yet. Picture of attempt # 6.
