Instructions

Cassava cake

Prepare a steamer big enough to fit an 8-inch round pan. Fill the steamer pot with enough water for an hour of steaming, and start boiling the water while preparing the cake batter over medium heat.

Stir grated cassava, coconut milk, vanilla, agar powder, sugar, and salt in a mixing bowl until smooth. Pour the batter into the cake pan.

Once the steamer is ready – the water is boiling, and there is plenty of steam – place the pan in the steamer and steam the cake for 50-60 minutes.

Let the cake cool completely before cutting. I usually let it chilled in the fridge overnight since it makes cutting the cake easier.
