1. Before cooking, kelp needs to be soaked in clean water for 3-4 hours in advance until the hair rises, and then it can be cut into rectangles or knotted for later use.
2. Pour an appropriate amount of cold water into the pot, put the washed ribs in the pot, add the cooking wine and boil the water.
3. Remove the blood foam for about 5 minutes, and wash the blanched ribs with water.
4. Pour the blanched ribs and sliced ginger into the pot, add an appropriate amount of water, bring to a boil, turn to medium heat and cook for about 30 minutes.
5. After 30 minutes, add the kelp, turn to high heat and boil for 20 minutes. Add appropriate amount of salt to taste before cooking, sprinkle with chopped green onion.
Tips:1. Although it is also possible to buy knotted kelp directly, there is often sand in it, which also needs to be soaked and washed with water.
2. The saltiness of kelp varies after soaking, and the amount of salt can be adjusted according to personal taste.
