Corn on the rocky plateau of Ha Giang is found in rock crevices and grows in harsh climate conditions, so has a good taste and a characteristic aroma. The taste of corn in each noodle blends with the flavour of the northern mountains to create a unique dish.
Corn noodle soup is made the same way as traditional pho. However, corn is less sticky than rice, so making and slicing techniques are more difficult.
Making corn noodles also helps improve the value of corn kernels, thereby contributing to increasing incomes for highlands people.
Visitors to Quan Ba can enjoy a bowl of handmade corn noodle soup in Trang Kim village.
