1, after soaking in water, the kelp can be cooked for 5 minutes.

2, kelp soak time can not be too long, two or three hours is enough, soak time is too long, the nutrients in the kelp, such as water-soluble vitamins, inorganic salts, etc. will also be dissolved in water, the nutritional value will be reduced.

3, in the process of cooking kelp can put some spinach, so it will also be quickly cooked. Because spinach contains oxalic acid, can make the kelp quickly soften, easier to cook. This method is more effective, the disadvantage is that it may affect the flavor.
