Banh da Ke is a traditional product, which appeared a long time ago. Dry cake making process of Ke people is thought to be simple at a glance but in fact, it requires carefulness and skillfulness of craftmen. Main ingredient to make  Banh da Ke is rice which must be good type of rice and harvested for a long time so that its resin can be transferred into another substance melt into white rice.

Rice has to be cleaned softly so that its bran is still maintained. Then, rice will be dipped into ceramic bowls until it has sour taste and becomes bloated, then it will be picked out to be grinded. Nowadays, rice is grinded by machine instead of stone mortar which is much easier than before. Rice must be grinded carefully in clean water into white and smooth flour. Some people cook rice before grinding with uncooked one to make banh da soft enough.

After grinding rice into flour, craftmen start to make cakes by spreading flour on hot surface to have thin layers. Banh da Ke is spread twice to ensure thickness of the cake.

After the cake is cooked well, it is picked out carefully to avoid being torn or out of shape. The makers use a long and big tube of bamboo to put on one part of the cake, softly roll it a half round, then carefully put it down a bamboo grid and pick it out.

Before drying the cakes, people cover one face of the cake with uncooked sesame and punched peanut. This process also requires carefulness and skill to spread out sesame on the cake surface with a thicker layer in the middle of the cake.

Banh da is put on flat bamboo grids which are bigger than the cake size. When one face of the cake is almost dry, it must be picked up so that it is not stick to the grid and broken, then it is continued being dried. After being dried, the cake will be carefully protected. In the past, the cake used to be put in cool and high places to avoid getting wet; now it is often put in tight nylon bags.

Banh da Ke also goes through another process- grilling before being finished. This final process is rather complicated requiring skill and experience. Banh da is grilled on a bowl of burnt wooden coals. The maker has to hold cake in one hand and hold the bamboo tape fan in the other hand. She has to fan smoothly and constantly while rapidly turning over the cake. At that moment, the cake spreads out sweet smelling. The cake is often grilled by the female who are flexible and skillful.
