Siu Xian Cao raw material is cold powder grass.

Braised Immortal Grass has different names in different regions, Guangdong, Hong Kong and Macao call it Liang Fan, the Hakka people call it Xian Ren Ren (ban 三声), the Chaoshan people call it Grass Kuey Teow (草粿). Across the strait, the Taiwanese compatriots give it with taro puree, taro ball, peanuts and other ingredients, which becomes the delicious Braised Immortal Grass. But the main ingredient in the making of roasted fairy grass is actually a Chinese medicine - Liang Fan Cao (凉粉草).

Liangfenqiao is the above-ground part of the labiatae plant Liangfenqiao. It is also known as immortal grass, fairy grass. It is widely used in the production of herbal tea, functional beverages and food ingredients, and is the main ingredient of herbal tea such as Gadobao, Wanglaoji, and Heqizheng, as well as the main additive in certain food products such as tortoise jelly and cool powder.

Liangfenqiao mainly has sugar, flavonoids, phenolic acid, terpenoids, such as langfenqiao polysaccharide, galactose, arabinose, zi Yunying glycoside, rosemarinic acid glucoside, oleanolic acid and so on. It is precisely because of its richness in gelatinous polysaccharides that Liang Fan Herb is able to be used in the preparation of Liang Fan. However, this gel is not enough to freeze, and the help of starch is needed.

Origin of Roasted Immortal Grass:

Immortal grass is said to be famous for the dried immortal grass from Jiuhua Mountain in Miaoli County, Taiwan. Decades ago people ate Xiancao mainly by cutting it into small cubes and simply adding sugar water and crushed ice. Although it was also served hot, it was better eaten frozen. Served with lentils soaked in sugar water with popping black pearls, it's icy and refreshing.

Talking about the origin of roasted immortality, it has something to do with the Hakka people in Miaoli, most of them are Hakka people, who came from Fujian and Guangdong hundreds of years ago, and the practice of roasted immortality is similar to Guangdong's cold noodles, which were not used in Taiwan before this, and it is a bit of an anti-Hakka as a famous snack in Taiwan, but the Taiwanese don't take it seriously.
