Many first-time customers mistake it for a kind of porridge, but it looks like udon soup. Vinh in Nghe An Province is where you can most easily find an eatery selling this since locals are not averse to eating porridge noodles at any time of the day.
According to the owner of an old restaurant in the central town, the reason for the name is that the broth must be as thick as porridge. The noodle must be cooked for a few minutes unlike vermicelli and pho in the north, which are dipped in boiling water for just a few seconds.
To make this noodle, the chef often mixes wheat and rice flours. The owner of a popular porridge noodle shop on Hong Bang Street said the flour is mixed with water before being kneaded, rolled and cut. All of it is done by hand.
The noodle, after being cut, is boiled and the water is drained. It will be boiled one more time when there is an order before it is ready to be served. “An experienced chef will add one more step of putting the noodles in cold water so that they are chewy but not sticky,” the owner said.
