1. Steaming sea urchin takes 5 minutes. Sea urchin is an easy-to-cook food and does not need to be steamed for a long time. Once the sea urchin is steamed for too long, the tender texture will be easily affected. If the sea urchin is steamed for too short a time, it may become raw, unhygienic or pose other safety risks.

2. Buy fresh sea urchins, rinse them repeatedly with water, and prepare gloves, scissors, and spoons. There is a cut surface on the sea urchin, and the cut surface has the mouth of the sea urchin. Wear gloves on your hands and use scissors to cut open the mouth of the sea urchin. Pick up the sea urchin, pour out the sea water from the sea urchin, and wash it under clean water. Pick up the prepared spoon, move along the shell of the sea urchin, open the internal organs of the sea urchin, and scoop out the yellow color of the sea urchin. There will be residue of internal organs on the surface of the removed sea urchin. Rinse it in the sea water just poured out of the sea urchin. When no black and red substances are visible on the surface, it means that its internal organs have been removed, and what you get is clean sea urchin yellow.
