According to my many years' experience in dry sea cucumber, I first choose sea cucumbers with good quality and complete body shape. Boil the selected sea cucumbers in a stainless steel pot, 3. Soak in an oil-free heat preservation barrel for five hours, then take out the soft sea cucumber, cut open the stomach with a knife, and wash the mud, sand and intestines in the stomach. Pour the cleaned sea cucumber into a heat preservation barrel, add boiling water and soak it for 65438.
