Ha Giang has rich fields with many types of tasty types of rice, therefore Bac Me lam rice has become an unique dish of the Tay communities.
The way to make this kind of lam rice is very simple. Glutinous rice is cleaned and filtered, mixed with salt and then put on a tube that is made of bamboo, along with water from a mineral stream. The cooking tube has one solid end and another end sealed by banana or phrynium leaves. After this preparation, the tube is roasted on the fire or burning coal for about an hour, until the tasty smell of glutinous rice spreads widely over the pot. To eat this rice, the outer burned cover of the tube is removed with a knife to reveal the inner white cover, and after that, the white cover is also removed. Now the lam rice has a tube shape with a light membrane of bamboo around which adds an unique taste to the rice.
