1 Wash the bitter bamboo shoots and remove the old parts. Cut each bamboo shoot in half with a knife. Boil the water in the pot, pour in the bitter bamboo shoots, fish them up after the water boils again, let them cool, and pack them in batches with fresh-keeping bags. (each bag is the amount to be eaten once)

2, canned storage preservation method. Families without refrigerators can use the method of canning. Pickle jars, cans, bottles and other containers with a sink at the neck are the most suitable for holding 5- 10 kg. The first two methods are adopted to make bitter bamboo shoots into bamboo strips or slices, which are respectively packed into washed cans, pressed while being packed, and a proper space is reserved at the mouth of the can. Then, the mouth of the can is sealed with washed bamboo shells, palm leaves, grass braids, etc., and the cover is covered. Finally, water is slowly injected into the sink to cover the edge and isolate the air. If you use a container without a water tank, you can choose another water tank, put the bamboo shoot tank upside down in the water tank, and then fill the water tank with water to cover the tank mouth, and the water depth should not exceed the filler at the tank mouth. Pay attention to adding fillers after each feeding, and change water, inject water and check frequently to prevent the bamboo shoots from deteriorating due to water leakage. This method can guarantee the quality of 12 months.
