Dry sea cucumber needs to be soaked in clear water for 24-48 hours, and then boiled in boiling water for 40-60 minutes. The sea cucumber will soften and taste better. Cooked sea cucumber can be soaked in clear water for 24-48 hours until it becomes soft, and then it can be eaten. Please note that due to the different sizes and varieties of sea cucumbers, the soaking and cooking time may be different, so it is best to adjust it according to the actual situation.
