1, kelp soaked in water, boiled for 5 minutes and ready to eat. The soaking time of kelp should not be too long, two or three hours is enough.

2. Tips for cooking kelp: Soak kelp in rice water or salt water before cooking, add some vinegar to the water, and soak it for about 1 hour before cooking, so that it can be cooked quickly. This method is simple and convenient, and it is very suitable for use. You can put some spinach in the process of cooking kelp, which will also cook quickly. Because spinach contains oxalic acid, kelp can be softened quickly and boiled easily. This method has a good effect, but the disadvantage is that it may affect the taste.
