# What You’ll Use:
→ Sponge Cake
01 - 4 large eggs, separated
02 - 5.6 oz granulated sugar, divided
03 - 2 fl oz whole milk
04 - 1.7 fl oz vegetable oil
05 - 2.5 oz cake flour, sifted
06 - 0.35 oz cornstarch
07 - 1 tbsp hojicha powder
08 - 1/4 tsp salt
→ Hojicha Cream
09 - 6.8 fl oz heavy cream, chilled, minimum 35% fat
10 - 2 tbsp powdered sugar
11 - 2 tsp hojicha powder
→ Filling
12 - 1 ripe mango, peeled and sliced into thin strips
# How-To:
01 - Preheat oven to 340°F. Line a 9 x 13 inch baking tray with parchment paper.
02 - In a large bowl, whisk separated egg yolks with 2.8 oz sugar until pale and creamy. Add milk and vegetable oil, mixing until smooth.
03 - Sift together cake flour, cornstarch, hojicha powder, and salt. Fold into the yolk mixture until just combined, avoiding overmixing.
04 - In a clean bowl, beat egg whites until foamy. Gradually add remaining 2.8 oz sugar and continue beating to stiff peaks.
05 - Gently fold the whipped egg whites into the yolk-flour mixture in three additions, preserving airiness and avoiding deflation.
06 - Transfer batter to prepared tray, smoothing the surface evenly. Tap the tray gently to release air bubbles.
07 - Bake for 13 to 15 minutes until the cake springs back when lightly pressed in the center.
08 - Remove from oven while still warm. Invert cake onto a fresh sheet of parchment paper. Carefully peel away the original baking paper and cover loosely with a clean kitchen towel. Allow to cool completely.
09 - Whip chilled heavy cream, powdered sugar, and hojicha powder to medium-stiff peaks, creating a smooth filling.
10 - Once sponge has cooled, spread hojicha cream evenly across the surface. Arrange mango strips along one short edge of the cake.
11 - Using parchment paper as a guide, gently roll the cake from the mango edge, forming a tight spiral. Wrap in parchment and refrigerate for at least 30 minutes to set.
12 - Trim the ends for a neat presentation. Slice with a sharp knife using gentle sawing motions and serve.
