The sponge cake roll goes by many names. In France it’s known as a ‘roulade’ and can be seen at Christmas time as the elaborate Bûche de Noël or ‘yule log’ covered in thick chocolate icing and miniature meringue mushrooms.
Also known as the Swiss or jelly roll, the sponge cake roll is a thin layer of sponge baked in a sheet pan. Cooled on a kitchen towel, the sponge cake is then spread with a filling such as freshly whipped cream or in this case, cream and passionfruit butter, and then rolled and sprinkled with icing sugar. When sliced, the sponge cake has a beautiful pinwheel pattern.
Most of my experiences with sponge rolls have been with the packaged variety. This translates to preservative-laden cake filled with fake cream, and pales in comparison to the real thing.
