soak in clear water for 2-3 hours before cooking, and change the water several times in the middle. In order to ensure that kelp is fresh and delicious, it can be boiled in clear water for about 15 minutes, and the time should not be too long. The soaking method is as follows: (1) Steam dried kelp in a steamer for 3 minutes, rub it with alkaline noodles after taking it out, and soak it in clear water for 2-3 hours. It is crisp and tender when eaten, and has no fishy smell. When boiling kelp with water, the cooking time should not be too long, otherwise it will become harder and harder. If the cooking is hard, adding some vinegar can also soften the kelp; Or put a few spinach into it when soaking, which has the same effect. (2) After the kelp is soaked in water and washed, it is quickly scalded in boiling water, which is sanitary and can remove the fishy smell of seawater, and the color becomes beautiful, which is very suitable for cold dishes. Kelp is rich in nutrition, but it is not easy to cook, because its main component, algin, is not soluble in water, but it is soluble in alkali. When the water contains alkali, algin will absorb water and swell and become soft. According to this feature, kelp can be soaked in rice, which is easy to be soaked, washed and tender when cooked. Some kelp can also be cooked with a little edible alkali or baking soda, but be careful not to add too much alkali. The kelp is rich in nutrients, especially iodine, and has good medicinal value. It is a good green food.

kelp sold in the market now is mostly dry goods, which need to be cleaned and soaked after purchase. However, many people like to soak kelp for a long time after buying it back, thinking that it can fully absorb water. In fact, this practice is wrong. Because after soaking for a long time, the nutrients in kelp will be lost, and the salt will be lost in large quantities, so that kelp tastes tasteless and its nutritional value will be reduced.

Tips

The correct way to process kelp is to soak it as you eat it. It is not necessary to soak it for a long time, usually about 15 minutes.

The aquatic kelp in the market is often soaked for a few days, which has low nutritional value and is unsanitary. It should not be too long. When cooking, you can try to pinch hard and soft by hand. Once it is soft, stop the fire immediately.
