1. First, prepare scissors and towels and an appropriate amount of ice water. Hold scissors in one hand, grab the sea urchin with a towel in the other, and then open the sea urchin's mouth with scissors.

When the top of it is opened, you will see the sea urchin eggs inside.

3. Open the small hole at the top of the sea urchin, then take out the yellow sea urchin with a clean spoon and soak it in salty ice water.

4. After half an hour, take out the sea urchin eggs, wash all their internal organs by hand, and then suck up the water on their surfaces with a clean kitchen. At this time, fresh sea urchins have been treated.

5. The removed sea urchin eggs can be eaten directly, or mixed with eggs to make egg liquid, then put into sea urchin shells and steamed in a pot before eating.
