Bullacta haitanensis

Bullacta haitanensis, commonly known as "spitting iron" in Yuyao, is a mollusk with a thin shell and mucus on its surface, which is as big as a snail. Bullacta exarata is rich in protein, calcium, phosphorus, iron and various vitamins, and it is a popular seafood with delicious taste and high nutritional value. Yuyao has a coastline of more than 100 miles, and there is a large area of low tide beach along the coast of Hangzhou Bay, which is not only large in area but also fertile in soil, and is rich in seafood resources, among which the yellow mud snail produced in Linshan, Simen and Xiaocao 'e Town in the north is the most famous. The yellow mud snail produced by Simen and Xiao Cao 'e has a long head, yellow body, thick fat and particularly delicious taste, which is quite influential in Shanghai. The yellow snail in Yaobei was recorded as early as the Song Dynasty. According to the old records of Yuyao, the quality of yellow mud snail in Yaobei is the best when peach blossoms are in full bloom. At this time, the mud snail has just long hair, no mud in its body, is sterile and tastes particularly delicious. The "osmanthus mud snail" produced in the Mid-Autumn Festival is not as good as the "peach mud snail" produced in March of the lunar calendar, but it is also rich in fat and extremely delicious. Snails eat in different ways and have their own characteristics. Generally, cooking is very suitable for meals, but locals prefer to marinate with wine stains. The specific production method is as follows: select a large and fresh yellow snail, screen the mucus on the surface of the snail, wash it, remove water, put it in a container, add some salt and yellow wine, then seal the container and marinate it for about a week. Take it out then, and it will smell strange. Because the mucus and viscera of mud snails contain a toxin, some people who are allergic to this toxin may have symptoms of facial edema and stiff toes after eating mud snails (especially pickled mud snails), so they need to be extra careful. In addition, the mud snail is rich in nutrients, and once it is infected with germs, it is easy to multiply in large numbers. Eating this unclean mud snail is easy to cause diarrhea, so it is also necessary to be careful. It is best to add rice vinegar and other seasonings when eating mud snails, which can not only sterilize, but also increase the taste.
