Instructions
- Preheat your oven to 350°F (175°C) and line a quarter sheet pan with parchment paper, ensuring it fits snugly to prevent sticking.
- In a bowl, whisk together the yomogi powder with boiling water until it forms a smooth paste.
- In a separate bowl, mix egg yolks, oil, and milk with the yomogi paste. Sift in the flour and cornstarch, whisking until your batter is silky and well-combined.
- Using a stand mixer, beat the egg whites with cream of tartar until frothy. Gradually add sugar and whip until you achieve stiff peaks.
- Gently fold the whipped egg whites into the yolk mixture, being careful not to deflate the batter. Pour this fluffy blend into the prepared pan, leveling it evenly.
- Bake for approximately 15 minutes, or until the cake springs back when touched and is a lovely golden color. Place it on a wire rack to cool.
- For the kinako whipped topping, whip cream in a bowl until soft peaks form, then fold in the kinako.
- Once the sponge cake has cooled, spread the kinako cream evenly over the surface. Add a generous line of red bean paste, and carefully roll the cake using the parchment paper to guide you.
- Wrap your rolled cake tightly in parchment and chill it in the refrigerator for at least 45 minutes.
- Trim the ends to create a neat look, pipe extra cream on top, and dust with kinako before slicing.
