Peel the pulaka corms and cut them into large chunks.
If using banana leaves, wrap the pulaka chunks in the leaves to form parcels.
Place the pulaka parcels (or plain chunks) in a steamer.
Steam the pulaka for about 45-60 minutes, or until they are tender when pierced with a fork.
In a saucepan, combine the coconut milk, brown sugar, and salt.
Heat the mixture over medium heat, stirring constantly until the sugar is dissolved and the sauce is well combined.
Simmer for about 5-10 minutes until the sauce thickens slightly.
Once the pulaka is cooked, remove it from the steamer and unwrap it if using banana leaves.
Arrange the pulaka chunks on a serving dish.
Pour the coconut sauce over the pulaka.
Enjoy your meal!
