The iconic sweet of Aceh, eaten above all at Eid. A soft dough of glutinous rice flour mashed with ripe banana is wrapped around a sweet filling, sealed inside a folded banana-leaf parcel and steamed. The classic filling is unti — grated coconut cooked down with palm sugar — though a smooth srikaya custard of egg, coconut milk and sugar is just as common. Steaming sets the dough into a tender, faintly sticky cake perfumed with banana and the warm scent of the leaf. Made in quantity for the festive open house, it is offered to the stream of visitors who call during the holidays.
Timphan is a traditional Acehnese kue with no recorded date of origin, passed down as a domestic festive food rather than a restaurant dish. It is bound up with Aceh's Islamic holiday culture: across the province it is among the sweets most strongly associated with Hari Raya, prepared in batches for the open-house visiting that follows the fast, which gives rise to the local saying that a holiday in Aceh is not complete without timphan. The use of glutinous rice, coconut, palm sugar and banana leaf places it firmly within the broader Malay-Indonesian family of leaf-wrapped steamed kue.
Unwrap the warm parcel and the dough is soft, supple and lightly sticky, scented with banana and the grassy steam of the leaf. Bite in and the sweetness comes from within — the unti filling is moist, chewy with coconut and dark with the caramel of palm sugar, or, in the custard version, silky and eggy. The cake itself is only mildly sweet, so the filling carries the dish, and a faint salt note keeps it from cloying. Best eaten fresh and still warm from the steamer.
Glutinous rice flour is almost pure amylopectin and contains little of the amylose that makes ordinary rice set firm, so on steaming it cooks into a soft, cohesive, stretchy mass rather than a crumbly one — the source of the cake's characteristic chew. Mashed ripe banana enriches the dough and adds natural sugar and aroma. The banana leaf is the cooking vessel: passed briefly over a flame to wilt it so it folds without splitting, it both holds the soft dough in shape during steaming and releases a grassy, faintly sweet fragrance into the cake. For the unti, palm sugar is melted and cooked down with the coconut until it caramelises and thickens enough to hold together.
Variations
The two classic fillings are unti (coconut and palm sugar) and srikaya (coconut-egg custard); some cooks fold a little jackfruit or durian into the dough for aroma. Timphan asoe kaya refers specifically to the custard-filled type, while plain banana-dough versions also exist. Where banana is scarce some use mashed pumpkin or sweet potato in the dough, and the parcels may be tied or simply folded.

How it's made
8 steps · 45 min
- 15 min
Soften the banana leaves over a flame until pliable, then cut into rectangles.
Watch outPass the banana leaves over a flame just until they wilt supple — softened leaves fold without splitting and won't tear open in the steamer.
- 212 min
Cook grated coconut with palm sugar and a pinch of salt until thick and caramelised to make the unti filling.
- 38 min
Mash ripe banana, then knead with glutinous rice flour and a little coconut milk into a soft, smooth dough.
- 43 min
Take a portion of dough, flatten it and spoon the filling into the centre.
- 52 min
Fold the dough over to enclose the filling completely.
- 63 min
Place each parcel on a banana-leaf rectangle and fold into a sealed packet.
- 730 min
Steam the parcels over boiling water until the dough is cooked and firm.
Watch outSteam until the dough is cooked and firm — glutinous flour turns soft, cohesive and stretchy when done; underdone it's raw and pasty in the middle.
- 82 min
Cool slightly and serve warm in their leaf wrappers.
