    What is grass jelly (涼粉)?

    Grass jelly is a very common and classic summer dessert among Hong Kong, Macau, Taiwan, mainland China and southeast Asia. In Cantonese, it called leung fan (涼粉). On the other hand, in Taiwan grass jelly known as xian cao (仙草).

    Sometimes, they add to boba drinks and shaved ice. Often, it is cut into cubes and served with syrup, condensed milk or milk. And, some like to add fruits as well.  

    What is grass jelly (涼粉) made of? 

    grass jelly from scratch ingredients

    Grass jelly is made from dried and oxidized platostoma palustre plants (Mesona chinensis). And, they are a member of the mint family. It is made by boiling the oxidized stalks and leaves of platostoma palustre with potassium carbonate or baking soda. Then, thicken it with a little cornstarch or potato starch. After cooling off, it forms a jelly-like texture.

    What is leung fan (涼粉) taste like?

    Asian grass jelly has its fragrance, mild herbal taste and slightly bitter. Actually, just eating it is very plain.

    What goes well with leung fan dessert (涼粉)?

    Most people like to add syrup, condensed milk, honey, coconut milk and fruit to go with grass jelly. Some use it to make drinks and shaved ice too. 

    Cooking tips for how to make grass jelly from scratch:

    • Wash and rinse the dried platostoma palustre in order to remove dust and sand.
    • Pour water and baking soda into a big pot. Then, add washed mesona chinensis and boil it. When it's boiling, turn the fire to small and simmer for 30-45 minutes. Normally, it takes around 5 hours to boil them if you do not add any baking soda. By adding baking soda or potassium carbonate, it speeds up the process for around 30-45 minutes.
    • To prevent overflowing while boiling, I put a plate on top of the herb.
    • You may have noticed some white stuff floating on top. Don’t remove them, it’s from the plants and it helps to hold the grass jelly better.
    • After boiling the plants, wait until it cools off. Then, use your hands to rub the plants and mix the liquid, so more slimy things will come out from the plants.
    • Use a strainer bag to remove big pieces of plants. After, I use a fine strainer twice to remove small pieces of the plants. As a result, the liquid is around 4-4.5 cups. ( I like the 4.5 cups texture better.)
    • In a small container mix water and cornstarch or potato starch to thicken the liquid. Potato starch has better texture; however, corn starch works well.
    • Let the grass jelly cool off and refrigerate it for a few hours, it will form jello like.
    • Cut into cubes and serve them with honey, syrup or condensed milk and milk. You can even add fruits such as mango, strawberry and kiwi.

    FAQs:

    Where can I purchase dried platostoma palustre?


    If you are in Asia, often you can purchase them in Chinese herbal medicine stores. You can find some online, if you are in the states or other areas. 
    dried platostoma palustre plant or dried grass jelly plant

    What is the health benefit of eating grass jelly?


    In Chinese herbal medicine, grass jelly is great to consume in hot summer because it has cooling properties.

    Does grass jelly contain gelatin?


    No, it doesn't contain gelatin. When you boil the dried platostoma palustre with baking soda for a while. There are some chemical reactions, the slimy stuff will come out from the herb, especially when you are rubbing it. The slimy stuff and cornstarch will hold and form like jello.

    Can I use grass jelly powder?


    Yes, you can use the powder form, but it will be different instructions. This Asian grass jelly recipe mainly shows how to make it from scratch and I feel safer because I know what the ingredients are.

      I never knew how grass jelly is made. These instructions with photos are great. Now I know how to make my own. It’s been my favorite since I was a child. I especially love Leung fun bing (grass jelly and red bean shaved ice). Yum!
