# What You Need:
→ Sponge Cake
01 - 4 large eggs, separated
02 - 2.8 oz granulated sugar, divided
03 - 1/4 cup whole milk
04 - 3 tbsp vegetable oil
05 - 2.5 oz cake flour, sifted
06 - 0.3 oz cornstarch
07 - 1 tbsp hojicha powder (roasted green tea)
08 - 1/4 tsp salt
→ Hojicha Cream
09 - 3/4 cup heavy cream (minimum 35% fat), chilled
10 - 2 tbsp powdered sugar
11 - 2 tsp hojicha powder
→ Filling
12 - 1 ripe mango, peeled and sliced into thin strips
# How To Make It:
01 - Preheat the oven to 340°F. Line a 9 x 13 inch baking tray with parchment paper.
02 - In a large bowl, whisk egg yolks with 1.4 oz sugar until pale and creamy. Add milk, vegetable oil, and mix 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 1.4 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 the batter into the prepared tray, smoothing the surface. Tap the tray gently to remove air bubbles.
07 - Bake for 13–15 minutes or until the cake springs back when lightly pressed.
08 - Remove from oven. While still warm, invert the cake onto a fresh sheet of parchment. Carefully peel off the 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 the sponge is cool, spread the hojicha cream evenly over the surface. Arrange mango strips along one short edge.
11 - Using the parchment, gently roll the 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.
