1, winter bamboo shoots are boiled in hot water. If cold water is used, winter bamboo shoots will be cooked in the pot for a long time, which will easily get old and destroy the fresh and tender taste of winter bamboo shoots.

2. Boiling with hot water will neither lose the nutrition of winter bamboo shoots nor cook them. Winter bamboo shoots contain more oxalic acid, which needs to be removed by blanching. If they are not eaten directly by blanching, too much oxalic acid is not good for human health.
