i saw this swiss rolls on the internet and try it my self ( its not my idea, i found some pics on japanese websites)
you can also use it on top of a round cake or square.
very nice when they donnot eat or may eat marzipan or rollfondant.
spray cooking spray on your baking sheet and put your bakingpaper on it .
put uncolored spongecake batter in a piping bag or bottle and put some tips of the strawberries on the parchment.
freezing it for 10 minutes.
remove the tray from the freezer
Now spray the crowns of strawberries on the parchment paper with green colored batter.
put it again 10 minutes in the freezer
remove again from the freezer.
now you go finish the strawberry with red colored batter .
for the last time you put the bakingsheet 10 minutes in the freezer.
set your oven to the correct position
get it out of the freezer again.
Divide the last uncolored batter over the bakingsheet and bake this for about 10 minutes.
make sure you donnot overbake the spongecake becouse you cannot roll it well then and you get cracks like my first swiss roll , you can see the cracks on the picture.
when its out of the oven you can roll it between sheets of greased baking papier or you can take a put wet cloth on it a few minutes .
when you peel the bakingpaper of you get this look.
you can made all kinds of patterns on it , you also can make a picture with a sharpie pen on the baking paper and put that on the bakside so you can fill that in,note that you put letters in mirror writing on it .
now you cut the sides away and put the filling on it .
roll the swissroll between some greased bakingpaper.
