Weight the dried platostoma palustre plant 40 g which is around 3 cups
Wash and rinse the dried platostoma palustre plant to remove dust and sand
In a big pot, add 8 cups of water, ½ teaspoon baking soda, washed the platostoma palustre plant and boil them on high fire. When it’s boiling, turn the fire to medium small and simmer for 30-45 minutes.
After that, let it cool off, use your hands to rub the plants to get the slimy thing out and mix with the liquid.
Then, use a strainer bag to remove the big pieces of the plant.
After that, use a fine strainer to remove smaller pieces of the plant. Remember to do this step twice.
The result of liquid is around 4-4.5 cups. (I like 4.5 cups texture better.) Next, in a small container mix 4 tablespoons of water and 4.5 tablespoons of cornstarch or potato starch to thicken the liquid. Potato starch has better texture; however, cornstarch works well.
Pour the thicken mixture into a container and refrigerate for 3-6 hours
