Processing Method: Soak in water for 1 to 2 days (depending on size) and change the water at least once a day. Put into boiling water and bamboo sheet should be laid underneath. Boil for 30 minutes, turn off the heat and leave the lid covered until the water cools down. Take out and rinse with water. If the fish maws are still not softened, soak them in water for another 10 hours until softened.
