1 Fresh sea urchins should be cleaned with clean water after they are bought back. Prepare a pair of gloves and a pair of scissors and a clean spoon. Spread the newspaper on the table, take a sea urchin and fix it on the newspaper. 2. The scissors in your hand should be inserted from the bottom of the sea urchin, that is, the mouthparts, and cut out a round mouth, and the mouthparts of the sea urchin should be removed. Pick up the sea urchin by hand and pour out the liquid in it from the cut mouth. At this time, most of the liquid poured out is seawater in the sea urchin, so don't throw it away and put it in a bowl for later use. 3. Take out the prepared spoon by hand, hold it in your hand, and slowly insert it from the mouth cut on the surface of the sea urchin. After entering, gently open the viscera of the sea urchin, then insert it along the sea urchin shell and dig out the yellow sea urchin yellow inside. There will be residual viscera and some dirty algae on the surface of the sea urchin yellow after it is taken out, but it can't be washed with clean water, so it should be directly put into the sea water poured from the sea urchin. 4. The sea urchin yellow is slowly rinsed in seawater. When no black substance can be seen on its surface, it means that all its internal organs have been removed, and the obtained sea urchin yellow is clean and can be eaten directly. If you want to eat raw sea urchin yellow, you'd better take it out and mix it with mustard, soy sauce and balsamic vinegar, so that people can taste the delicious taste of sea urchin. 5. The method of eviscerating fresh sea urchin is not complicated. In addition to the above method, you can also take out its internal organs when taking the sea urchin yellow, put it in a cool white pot after taking it out, and gently shake it a few times, so that the internal organs and the sea urchin yellow can be automatically separated. At this time, the black part in the basin can be taken out, and the complete sea urchin yellow can also be obtained.
