# Components:
→ 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
10 - 2 tbsp powdered sugar
11 - 2 tsp hojicha powder
→ Filling
12 - 1 ripe mango, peeled and sliced into thin strips
# Method:
01 - Preheat oven to 340°F. Line a 9 x 13 inch baking tray with parchment paper.
02 - In a large bowl, whisk 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.
04 - In a clean bowl, beat egg whites until foamy. Gradually add remaining 2.8 oz sugar and beat to stiff peaks.
05 - Gently fold the meringue into the yolk-flour mixture in three additions, being careful not to deflate the batter.
06 - Pour batter into prepared tray and smooth the surface. Tap tray gently to remove air bubbles.
07 - Bake for 13 to 15 minutes until the cake springs back when lightly pressed.
08 - Remove from oven. While still warm, invert cake onto a fresh sheet of parchment. Carefully peel off baking paper and cover loosely with a clean kitchen towel. Let cool completely.
09 - Whip chilled heavy cream, powdered sugar, and hojicha powder to medium-stiff peaks.
10 - Once sponge is cool, spread hojicha cream evenly over the surface. Arrange mango strips along one short edge.
11 - Using parchment as a guide, gently roll cake from the edge with mango, forming a tight spiral. Wrap in parchment and chill for at least 30 minutes to set.
12 - Trim the ends for a neat finish and slice to serve.
