Mold
Separate eggs into yolks and whites.
Make chestnut batter--Mix 50g of chestnut puree and 50g of sugar. Add a yolk and mix them.
Put 30g of rice flour and mix them.
Make white chocolate batter--Melt 50g of white chocolate in a double boiler. Add 40g of yoghurt and melt them together. When the chocolate melted completely, take it off the heat.
Add 1/2Tbsp of sugar and mix them well. Add a yolk and mix them.
Put 30g of rice flour and mix them.
Make meringue with white of the two eggs and the 30g sugar.
Mix 1/2 of the meringue and the chestnut batter. Put it into a mold. Smooth the surface.
Mix another 1/2 of the meringue and the white chocolate batter. Put it into a mold. Smooth the surface.
Put the mold in a steamer. Put it on chopsticks to make a space under it. Steam it for 20 minutes over a high heat. (*Water in the steamer should be boiled when you put the mold. *Put a cloth under the lid to avoid dews dropping on the cake.) Unmold and put the cake on something like a toasting net to cool it. During cooling it, cover it with a cloth to keep it moisture.
