This dish is made from fermented soybeans that have been boiled until tender and pulverized. Then they are wrapped in banana leaves and grilled. If made into thin sheets, it is called “thua nao kaep”. The dish made with this kind of bean is believed to be an influence of Tai Yai people. (Rangsan Chanta and Rattana Phromphichai, 1999, p. 2636). A beaten egg can be added instead of pork, which can give it a better taste. (Sumali Thabun, personal communication, June 27, 2007).
