A kind of long sea-like mussel is called how to eat it. I took a picture, but I wouldn't put it on it.
The above helps you answer correctly: razor clam. Processing method: clear water immersion, sand spitting varies from source to source! Take it out at least one hour, heat the pan, add a little oil, add shredded onion and ginger at seven minutes oil temperature, add razor clam (with shell) and stir fry, add a little salt and cook in cooking wine, stir fry for six times, pour in thin sauce (generally starch) and stir fry until juice, and then serve: salty and delicious, enjoy yourself!
