Baking disaster

The curiousity in me prompt me to experiment with the Brazilian cheese bread recipe today.

I wondered:
1) What makes the Brazilian cheese balls rise?

Is it the egg? the cheese? or the tapioca flour with the mixture? or the blending process itself?

2) If the Brazilian cheese balls can rise, then I can make a sponge cake rise with the same technique, right?

I tried with exactly the same ingredients minus cheese and salt; plus choc chips. And it turned out to be a disaster!

The balls rose so high that they eventually burst and showed hollow bread!

So, I added some salt to the mixture. This time the balls rose but to an extend. Still, the balls collapsed once taken out from the oven. Hmm...

A baking disaster day! Hope this didn't damper your enthusiasm in baking...
Baking is a process of trial and error itself. It's only by this that the baking industry will prosper and come out with more innovative and creative creations.
