Arachis hypogaea; kacang tanah. These Central American plants have been grown in Java for over two hundred years. Sir Thomas Stamford Raffles said they were grown near towns for the sake of their oil, which was used for cooking, as it still is. The Javanese also make a fermented peanut paste called oncom which is something like TÉMPÉ. NOTE: Peanut oil is often sold under the name ‘groundnut oil’.
