Porphyra

Porphyra is a kind of seafood. Because it is rich in iodine, it is an important material for treating goiter besides eating. The other functions of laver have also been mentioned above. In our daily diet, we might as well add more dishes containing laver.

In addition to its dietotherapy function, laver tastes delicious, especially after roasting, which is similar to that of oysters. At this point, we will mention seaweed. In fact, seaweed is laver, which is a trade name called Porphyra yezoensis. Seaweed products are divided into three categories: dried seaweed, seasoned seaweed and roasted seaweed. The snack pieces of seaweed that we usually eat belong to seasoning seaweed, while dried seaweed and roasted seaweed are mostly used to wrap sushi or put it in soup and noodles (especially Japanese and Korean restaurants). Seaweed is very convenient to use, especially when cooking for babies, it is directly wrapped in rice or fried and put into soup, noodles and wonton, which increases the taste and nutrition at the same time. However, seasoned seaweed contains more salt and other seasonings, and should not be eaten excessively.

Porphyra used to make soup in Chinese food is made by cutting fresh vegetables, washing them, making cakes and drying them, so we usually buy them plate by plate in dry goods stores. When cooking, it is soaked first, which is commonly used to make soup. Laver egg soup is a classic laver soup spectrum. Porphyra can also be cold-mixed, fried, stuffed and served as side dishes, with crisp and fresh taste.

● Soup in the heart

1. If the laver is blue-purple after soaking, it means that the laver has been polluted and is not suitable for eating.

2. Porphyra is too soft and rotten when cooked for a long time, so half an hour is enough.
