Green Tea Mousse Chocolate Cake

green tea mousse chocolate cake

I have come to a cookbook with very nice cake presentations.  It is from various bakeries in Japan.  This green tea mousse chocolate cake is my second attempt but with lots of alterations.  It is from Patisserie Kanae, Kyoto.  I changed the chocolate sponge cake totally as the original one needs egg white between five and six eggs.  I did not want to waste the egg yolks.  Mine needs three eggs and is soft.  I also changed the green tea cream as the original recipe may be difficult to set.  It uses only green tea powder and cream.  Mine includes gelatin and letting it set in the fridge overnight.  It requires whisking prior to the final assembly.  It’s velvet with green tea fragrance.

Chocolate Sponge Cake
36g Cake flour
15g Cocoa
9g corn starch
60g Sugar
3 eggs
30g melted butter

Preheat oven to 200C

Beat the sugar with egg over in bain marine till the temperature is slightly below 40C. Remove from heat.

Beat the egg mixture until pale and thick. Whisk at low speed for 1 minute.

Sift the flour mixture 2-3 times. Gently fold it into the egg mixture.

Add a portion of the egg mixture to the butter. Mix till well incorporated.

Fold in the butter mixture gently to the cake mixture.

Pour the cake batter on to a rectangle cake pan.  Bake for 4 minutes. Put a baking tray below the cake and bake for further 4-5 minutes.

Once it’s done I cut a 18cm square.  Use the rest to assemble another 18cm square.

Bloom the gelatin in ice water. Drain excess water when it becomes soft.
