This time is 3 to 10 minutes.

If it is dried kelp, it needs a longer cooking time to reach a cooked state because it contains less water. Dried kelp shreds need to be cooked for more than 10 minutes to ensure that the inside is fully cooked. If it is wet kelp shreds or partially processed kelp shreds, because it contains a certain amount of moisture, the cooking time is relatively short, about 3 to 5 minutes.
