Remove from the heat, strain through a fine sieve into a bowl, and set aside to cool to room temperature. Preheat the oven to 180 °C / 350 °F or if you are using a fan-assisted oven, then preheat it to 165 °C / 330 °F. Prepare the baking sheet. Line a 25 cm x 35 cm (9 x 13-inch) baking sheet with parchment paper, then grease the paper with butter. Evenly dust with flour, then remove any excess flour from the pan.

roll into a roulade
Take the baked sponge cake out of the oven. Using a pairing knife gently scrape into the edges of the cake. Invert the cake onto the prepared parchment paper. Carefully remove the parchment paper. Using a serrated knife, make two shallow (2 - 3 mm or 5/64 inch) horizontal cuts 2 cm (1-inch) apart on the shorter side of the sponge cake near you. While the cake is still hot, roll into a swiss roll. Use the incision to help you make the first move and use the towel and parchment paper to help you roll the sponge tightly. Place on a wire rack and set aside for 30 minutes.
