1, if you want to eat fresh kelp, you'd better not wash it with water, just steam it in a pot, then take it out and wash it, cold salad or stir-fry shredded pork.

2. If you want to store kelp, dry the fresh kelp and then store it. As long as it is not wet, it can be kept for a year or two, and it can be soaked in fresh water for half a day when eating.

3, you can also use fresh kelp to make sea knots, then steam them and put them in the refrigerator.
