The cooking of Indonesia's most populous island: sweet with palm sugar and kecap manis in the centre, saltier and hotter towards the east, with tempeh and tofu at nearly every meal.
Java is Indonesia's most populous island, and the Javanese its largest people. Their cooking grew among rice fields and around the courts of Yogyakarta and Surakarta, heirs to the old kingdom of Mataram, where palm sugar — gula jawa, 'Javanese sugar' — and kecap manis give the food its famous sweetness. Why the centre came to like it so sweet is often explained by the sugar plantations of the colonial era, though that is a story more than a settled fact.
The north coast looked outward. Ports such as Semarang and Surabaya traded with China, India and Arabia for centuries, and Chinese communities there brought tofu, noodles, soy sauce and spring rolls that Java made its own. Tempeh — soybeans bound into a cake by mould — is Java's own, and among its best-known gifts to the world.
Go east and the food changes: saltier, hotter, darker with petis, a thick black shrimp paste, and less sweet. Madura, across the strait from Surabaya, sends its sate sellers all over Indonesia.
