I did swiss roll before but have never try with decorated pattern on swiss roll. Since i bought a decorated swiss roll cookbook ( 彩绘蛋糕卷 ) from the Book Fair recently .So i quickly try my 1st decorated swiss roll with the most basic pattern, polka dot.

But i did not follow to the sponge cake recipe in this book or followed to the earlier 孟老师 recipe, instead i follow a recipe from my favourite cookbook that i bought from Shanghai. I am very pleased with this sponge cake recipe, easy to make (making chiffon method) and yet resulted a spongy and flexible swiss roll cake. I will use this basic swiss roll recipe from now onwards..



While i went out to fetch my son who having tuition in school, i let my daughter to pipe the patterns for me. So this was how she made the polka dot, not same size and you can noticed she pipe a heart shape also, hehehe..

3. Place a new piece of baking/parchment paper over the sponge. Invert the sponge again.
