1. Remove stones and shells from seaweed, wash quickly, and cut into 2 to 3 cm lengths.

2. Put water and seaweed in a deep pot and let stand for about 1 hour.

3. Start over high heat. When the seaweed begins to dissolve, reduce the heat to medium and cook, stirring constantly, until dissolved.

4. When the bottom of the pot can be seen by drawing a line across it with a rice scoop, turn off the heat and pour the mixture into a container to prevent bubbles from forming.
