Fool proof Egg white Swiss Roll 简单蛋白瑞士卷

I baked this Egg White Swiss Roll 蛋白瑞士卷 few weeks ago and finds it nice so today I shall try again because the last time, I used a bigger pan and the layer is too thin for my liking.

I have been practising my swiss roll but yield no good result except for this recipe.  For my first attempt, I was delighted when it did not crack!!!  So today, I am doing it again just to be sure.

I lined the sweeten red bean to give it some design.  As for the filing, this has become my favourite as it does not melt easily and with less guilt too.

Learning experience: 

The texture is cottony soft and it is really easy to roll.  The sweetness level is just the right balance.

I was trying hard to cook the red bean whole and not mushy, thus the result was a little too hard.  I will need to try again and make it whole yet softer.  Thanks J for the feedback.  Appreciate it.

Am glad that overall, my gardening kakis like it.
