Boil your kettle, and place the kettle on a heat-resistant surface such as an electric stove. Add the water to the kettle and turn the heat to medium-high. Place the fish fillets in the boiling water, turn off the heat, and cover the pot. Let the fish cook for about ten minutes or until the fish flakes easily. Remove the fish from the pot with a slotted spoon and transfer to a large bowl of ice-cold water to stop the cooking process. The fish is ready to serve when it flakes easily.
