Notes
Fermented cassava has to be softened before mixing into the batter. Remember to take the hard string at the core of the cassava.
Mixing the fermented cassava into the batter is easy but needs to taken seriously. You really have to mix the egg sugar batter until thick and pale. Plus, the fermented cassava has to be soft. Otherwise the fermented cassava will end up at the bottom of the cake.
Cheese is actually optional. The cake itself is already very delicious and fragrant from the fermented cassava.
You can mix the fermented cassava with the melted butter. This way when you fold in the cassava into the batter, it saves time.
