It's a kind of snack widely enjoyed by the Luoyan people. Its component is the soybean milk, i.e. the green bean used to make vermicelli. First, place the green bean milk seeped when making the green bean powder under certain kind of temperature, ferment it until it gets sour and heat it to about eighty degrees. When you notice the surface bubbled like the mushroom, add a little amount of flavored oil and churn it up over and over. When the soup is boiling, pour down the noodle and stir it till the noodle looks like the paste. Finally add the prepared celery, leek, pepper oil, green bean and salt. You will find its taste excellent and appetitive.
