Wash the sea cucumber first, then add boiling water for 3 hours to make it soft again. After changing the boiled water, add a proper amount of borax (generally 500g seawater borax 100g), seal it with plastic wrap, steam it in a drawer for 3-4 hours, take it out, rinse it with clear water, and soak it in clear water. Generally, 500 grams of dry goods can send 3-4 kilograms of parallel imports. The sea cucumber made of borax is full in shape, elastic and less in nutrient loss.
It should be noted that the size and thickness of sea cucumbers are different, so the rising time is different. Small and thin sea cucumbers can swell in a shorter time, while solid and thick sea cucumbers take a longer time. Some are the same size, the same thickness, the same variety, and some are a dime. Sort out those that are sent first, and continue to send those that are not sent.
