The rolled cakes are very popular in Japan. They usually have whipped cream and fruits in it. But I made one with Mascarpone cheese cream and berry jelly and topped with black berries since I couldn't roll it well at all but wanted make it look pretty somehow. I thought it would be like rolling Maki-sushi, but it was different. Now that I think about it, I am not particularly good at rolling sushi either. But it tasted good. I guess I'll need to try it again!
