2. The second preservation method: after the small bamboo shoots are shelled, put them in the eye water and blanch them again (eye water refers to the time when the water bubbles before it is ready to boil). Don't use boiled water, or it will be boiled too thoroughly, and the taste will not be crisp after storage. Blanch it for two minutes and pick it up immediately. Then put the small bamboo shoots in a sealed bag, put in a proper amount of mineral water (about150g for one catty of bamboo shoots), seal them and put them in the refrigerator for strong freezing preservation. Putting mineral water in the sealed bag makes the bamboo shoots keep their original moisture and crisp and delicious taste.
