Palm sugar is the primary sweetener of Indonesian cooking across every region and every preparation type — present in sambals, curries, marinades, desserts, beverages, and preserves. Its near-total absence from Indonesian food writing as a subject in its own right, despite its presence as an ingredient in approximately 60% of Indonesian culinary preparations, represents one of the more significant blind spots in how Indonesian cuisine has been documented. Two palm sugars dominate Indonesian cooking, and they are not interchangeable: gula jawa (Javanese sugar, from coconut palm — *Cocos nucifera*) and gula aren (from the sugar palm — *Arenga pinnata*). The distinction matters technically, flavouristically, and culturally.
