Pallade Veneta - Sticking with tradition: Vietnam's glutinous 12-hour Tet cake

The wrapped cakes of glutinous rice, green beans and pork belly have for centuries been one of several dishes prepared in a frenzy at home specially for Tet, the Vietnamese New Year which begins on Wednesday.

Hong, 55, has laboured over the dish -- which must be boiled for 12 hours over a wood fire -- almost every year for the last four decades.

"We can buy ready-made banh chung but it doesn't create that Tet atmosphere," she said, explaining she enjoyed the process of cleaning leaves, soaking rice and pre-cooking beans in the very early morning.

"It keeps me busy, and it's tiring, but I still love making the cake myself."

According to an oft-told legend, the banh chung recipe was first prepared thousands of years ago by a Vietnamese prince who wanted to impress his father in a bid for the throne.

Pleased with the cake's flavour and impressed with his son's demonstration of respect, the king duly handed down his crown.

The banh chung are often laid at family altars as an offering to ancestors, who are widely venerated in Vietnam -- a communist country that is officially atheist but still steeped in Confucian social mores.

Many families no longer make them from scratch but for those that keep the tradition, the work usually falls to the elders of the family.

Hong's 23-year-old son Nguyen Dao Anh Khoi is already fretting over taking the helm.

"Our generation has so many other things to worry about, so I am not sure I can keep this up," he told AFP as he rinsed a mound of rice under an outside tap at their Hanoi home.

For now, he is happy to enjoy the rich and comforting cooking of his mother.

A self-described healthy eater who often prefers Western dishes, Khoi makes an exception for banh chung.

"It's a bit fatty and too starchy," he said. But "it's also delicious."

"I can't imagine a Tet without banh chung."
