When making roulades such as this one, there are a few tips to help them turn out right. First, after baking, turn the jelly roll cake out onto a clean kitchen towel that's been dusted with sugar to keep it from sticking. Then you will actually roll up the cake and the towel into a cylinder to help set the shape before unrolling, filling, and rerolling (this time without incorporating the towel!).
- Preheat oven to 180°C (approximately 350°F).
- Beat eggs and sugar.
- Add sifted cornstarch, orange juice and zest.
