Japanese food, in the eyes of many people, is a very high-end specialty food. Even in the eyes of the Japanese, eating Japanese food can only be eaten several times a month to improve the food. For China people, Japanese food is also more expensive, and there are very high regulations on all kinds of food, skills and collocation. Friends who often eat Japanese food can often see chefs making sushi with fish eggs. Orange fish eggs come from salmon or round fin fish, and black fish eggs come from sturgeon. What kind of fish does green caviar belong to?

Even with the development of modern science and technology, fish are not easy to produce green fish eggs, which is basically impossible in molecular biology. There are two sources of green roe, one is flying roe and the other is spring roe, which is made by adding jadeite food pigment. The Japanese call it "green cancer". Another estimate is that an emerald algae was used. The eggs of this algae are very similar. Its name is Hailazhu, and more people call it "sea grape".

Sea grape is an algae plant that grows in the ocean and belongs to a kind of algae. Sea grapes have no taste, the key is taste. A full seaweed explodes in the mouth, and the juice inside has no taste, but the unique taste makes people more and more addicted. Friends who love listening to ASMR will find that there are many small videos of eating sea grapes recently, because the sea grapes will make a "bouncing" sound, which is very eye-catching.

In Japanese cuisine, sea grapes have been used for a long time. As early as the middle and late edo period in Japan, sea grapes had appeared on the dining tables of ordinary people's homes. However, the popular eating method at that time was not to make sushi restaurants or pickled cold dishes with salt, but to make soba noodles with fresh sea grapes, tempura, raw eggs, goose and other foods. If only sea grapes are used as noodle code, it is called "hanging". This is clear soup buckwheat noodles, only seasoned with the taste of sea grapes, which is very fresh.

Japanese people like sea grapes for two main reasons. First, the high-grade fish eggs of sea grapes are very similar, not only the surface is crystal clear and full, but also the crispy juice can be obtained by biting the sea grapes, which is similar to the taste of high-grade fish eggs such as salmon roe and sturgeon roe. Secondly, sea grapes are very clean, because this kind of algae has high requirements for water bodies. Once the sea surface is polluted, the finished product of sea grapes will be ugly, and the surface will be covered with a layer of stains, so no one will buy it.

In addition to eating fresh sea grapes directly, the Japanese also like to eat iced Zhenhai red grapes in Ningbo. They will drink the washed sea grapes with ice, drenched with orange vinegar, pure honey red vinegar, white sugar and other ingredients, and taste sweet and sour, which is very delicious. Because of the crystal green of sea grapes, the Japanese often match this seaweed with tofu, and bluestone dishes give people a very beautiful visual feast.

Nowadays, sea grapes have entered the sales market in China, and the audience is getting wider and wider. Products made of various sea grapes are also deeply loved by young people. Unlike the Japanese who eat light food, in the food stalls in China, sea grapes are all pickled with vinegar, pepper and minced garlic, and the refreshing seasoning is matched with the bursting juice of sea grapes, which is very refreshing. The small particles of sea grapes can wrap a lot of juice and taste very delicious. I wonder if there is this kind of sea grape in the food stalls in your hometown.
