The sea cucumbers sold in the market are generally dry sea cucumber, which can only be cooked and eaten by soaking in water. In order to speed up the development of water, traders often soak sea cucumbers in alkaline water, which will destroy the nutrition of sea cucumbers. Some unscrupulous traders also add formaldehyde to the water, which increases the water content of sea cucumbers and seriously harms consumers' health.
The simple way to make sea cucumber with water at home is to fill a thermos bottle with boiling water, put the washed dry sea cucumber in (not too much), cover it tightly, take it out after 12 hours, open it along the stomach, take out the internal organs, wash it, soak it in cold water for 5-6 hours, and then cook it. According to different kinds of sea cucumbers, dry sea cucumber can deliver 500g1000g to 6000g.
Remember, when water is boiling, there should be no oil or salt in it. If there is oil, sea cucumber is easy to rot and melt; If there is salt, it is not easy to penetrate. For the larger sea cucumber, it can be cut into several sections after the first watering, and then watered for the second time.
