Tempe undergoes fermentation in a workshop in a home in Jakarta January 18, 2008. Indonesia's traditional soybean cake, known as tempeh, is a source of livelihood for millions of people, many of whom are now struggling to cope with spiralling soybean prices. The price of imported soybeans has more than doubled to 7,600 rupiah a kg from a year ago, driven by concerns about dwindling U.S. stockpiles and fears that dry weather could reduce soybean output in Argentina, the world's third-biggest soy producer.
