The art of cooking in Kawayan (bamboo) were taught by the natives living in Subic Bay called the "Aetas". 


During the Vietnam War, Americans used Subic as a base. The Americans were then fascinated with how Aetas survived with only a bolo (machete) and bamboo to survive, and asked the Aetas if they could impart their teachings. Thus, the Jungle Environment Survival Training (JEST) Camp was born.
