During my working trip to the southern province of Binh Dinh, I was lucky to enjoy the dish one last time before the COVID-19 pandemic spread in the country early this year. 

I will never forget the special taste of the dish which is a natural yellow colour (normal vermicelli is often white), the bun day threads are tough and fragrant with buttery fat from roast peanuts, hot chili and sour from the dipping sauce.

I decided to meet a local maker to learn how to cook the dish at home in Hanoi.

Le Thi Hoa, 50, in Bong Son Village of Hoai Nhon District, who has been making bun day for almost 30 years, said the process is rather complicated.

Differing from normal vermicelli which can be used with grilled pork known as bún chả or with broth such as bún vịt măng (duck and bamboo shoots), bún dây is most tasty when in mixed vermicelli style only.

The main ingredient is old rice. The best rice is left from the last rice season because this kind of rice helps to make the bun day more tough compared to that made from new rice. The rice should be soaked in water for an hour and then dried before soaking it again in ash water for six hours, said Hoa.

She said the ash water should be made from wood charcoal, particularly coconut charcoal because it helps to give the vermicelli a special fragrance.

“According to my experience, the good ash water decides the quality of vermicelli to ensure it is of a natural yellow colour, tough and tasty,” said Hoa, adding that the ash also helps to preserve bun day for a longer time.

After soaking in ash water, the rice should be ground to become wet dough then cooked over a small fire, but it needs regular stirring to ensure it doesn't get burned. This is the most difficult stage that makes the bun day tasty, she said, noting that after the wet dough is done, the maker has to take it out from the pot, let it cool then knead it well before putting it in a frame to press into thin threads.

The threads are round and the size of your palm. They all are steamed, said Hoa. "This process is often done by me because with my experience, I know when the bun day is cooked.”

The dish is more tasty when eaten cool and dipped in sauce which includes fried dried minced onions in cooking oil and fish sauce plus lemon juice, minced garlic, chili and sugar, said Hoa. Many diners, particularly young people, like mixing boiled pork belly and shrimp with the dish.

It is more enjoyable when topped with roast peanuts and fragrant herbs such as basil and coriander.

Hoa told me that Bong Son Village is the birthplace of bun day, where it has existed for a hundred years. It is also called banh day (dây cake) by many locals because of its size like a round loaf.

The loafs are often placed in a big basket by sellers in the market or around the village in the morning and afternoon.

A tourist from the northern province of Cao Bang named Ha Hai An, said every year she often visits her husband’s native village in Bong Son so it is a good chance for her to enjoy the dish. She said unlike fast food nowadays, bun day should be eaten in a leisurely way to enjoy its special taste and particularly the rich flavour of the fish sauce made from the Tam Quan sea fish.
