1. Cut the winter bamboo shoots to be used for blanching for later use.

2, fire, put the right amount of water in the pot.

3. When the water is a little hot, add some salt.

4. Boil and pour in the chopped winter bamboo shoots.

6. Open the pot cover, confirm whether the winter bamboo shoots are ripe, and finally take them out.

bamboo shoots can be eaten without water, but it's better to drown them. Winter bamboo shoots contain oxalic acid, so it is recommended to blanch with boiling water to remove oxalic acid before cooking. Because oxalic acid can be dissolved in water, 6% of oxalic acid can be removed by hot water. This practice is especially important for middle-aged and elderly people and pregnant women who need calcium supplementation.

The oxalic acid contained in bamboo shoots is not a component needed by human body. If a large amount of oxalic acid is ingested, the calcium absorption rate of human body will decrease, and it will also lead to kidney calculi's problem. Of course, you don't have to be too nervous. The absorption rate of oxalic acid in the body is not high, only about 1%, which has little impact on the human body. Only when it is ingested in a very large amount will it cause health problems. However, just in case, it's best to "import" bamboo shoots with water before eating them, and it's also convenient for cooking.
