(1) Use fire to heat it and then soak it in water for 1 to 2 days
(2) Change water frequently during immersion.
(3) Boil the water in the pot. Add sea cucumber and cook for 5-10 minutes. Turn off the heat and bake until the water cool down.
(4) if the sea cucumber is not soft, repeat step 3 until soft.
(5) Remove the internal organs of sea cucumber (the first removal does not need to be very clean. You can do many cleaning).
Note: Do not get in touch with oil when processing sea cucumber. Sea cucumber with oil will dissolve during boiling.
