kelp knots need to be cooked for 5-15 minutes, depending on the specific situation.

It is usually cooked in about 15 minutes, but if it is soaked kelp, it can be eaten after 5 minutes of cooking. When cooking kelp, it should be turned at any time, so that the kelp can be heated evenly. It should be noted that kelp should not be soaked for a long time, usually 6 hours. If the soaking time is too long, the nutrients in kelp, such as water-soluble vitamins and inorganic salts, will also be dissolved in water, and the nutritional value will be reduced.
