Another Steamed Sponge Cake

With some time on hand, I've decided to give it another try at the steamed traditional sponge cake, also known as 雞蛋糕. I've tried it twice already, so this will made my third attempt. Based on quizzine's new recipe again, I think this is a better sponge cake than my previous attempt. This time, it was with the addition of carbonated drink. The carbonated drink helped to aerate the cake. I used 7-up instead, reduced the sugar to 200g, and used 6 eggs. Unfortunately, I cannot get it to "smile" anymore!
