Acar Ketimun (Indo-Dutch Cucumber Pickle)
Acar means pickle, ketimun means cucumber, and this little bowl of sweet vinegar, chilli, and crunch is the cool note that lets an Indo-Dutch rijsttafel keep its balance.

Sambal Goreng Kentang
Created by
The Indo-Dutch rijsttafel would be poorer without these crisp potato matchsticks, fried first, then lacquered in sambal, ketjap manis, garlic, and tamarind.

The name already tells you almost the whole method, if you listen politely. Sambal is the chili paste, goreng means fried, kentang is potato. No mystery there. But let me tell you a secret: the trick of this dish is that the potato is not fried in the sauce. It is fried first, made crisp and dry, and only then quickly lacquered, so the chili-ketjap clings like varnish instead of turning the whole pan into sweet potato porridge.
This is the Indo-Dutch table speaking in its clearest household voice. Rijsttafel, rice table, became famous as excess: many little dishes, many spoons, the colonial appetite pretending to be hospitality. But in Dutch homes after the war, especially in families who came back from Indonesia with grief, memory, and recipes folded into suitcases, it became something smaller and more tender. A table set with white rice, a few sambals, chicken, beans, eggs, and always something crisp to wake the mouth.
Sambal goreng kentang belongs there. The potato is a New World traveler that found its way into Asian and Dutch kitchens by different roads, then met chili, tamarind, and ketjap manis, sweet soy sauce, at the Indo-Dutch table. History and cookery, they cannot be separated, not when a single bite carries plantation sugar, Javanese chile paste, European potato, and the Dutch talent for making a side dish do the work of a conversation.
Hou het altijd simpel. Cut the potatoes thin, rinse away their starch, dry them as if your reputation depends on it, and fry them until they sound crisp when stirred. The sauce comes last and fast. You're not stewing here; you're glazing. That is the difference between kentang kering, dry crisp potatoes, and sadness with chili.
Sambal goreng kentang entered Dutch domestic cooking through the Indo-Dutch rijsttafel tradition, which developed under Dutch colonial rule in the Indonesian archipelago during the nineteenth century and became common in the Netherlands after Indonesian independence in 1949, when Indo-European families repatriated in large numbers. The dish reflects a documented colonial table rather than a simple national category: potato, chili paste, ketjap manis, and tamarind meet in the small side dishes served around rice. In Dutch homes it is often called kentang kering, dry potato, because the potatoes are fried crisp before being coated, a practical detail that explains the whole dish.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Deep heavy pan or Dutch oven
- •Spider strainer or slotted spoon
- •Thermometer for frying oil
- •Wide frying pan
Instructions
- 1
Cut and rinse
Cut the potatoes into fine matchsticks, about 3mm thick. Rinse them in two or three changes of cold water until the water runs mostly clear. This is not fussiness. The loose starch is what makes potatoes cling together in the oil, and here each little stick must keep its independence.
- 2
Dry the potatoes
Drain the potatoes very well, then spread them on a clean tea towel and pat them completely dry. Wet potato lowers the oil temperature and spits back at you, for obvious reasons. Give them ten minutes in the towel if you can; dry potatoes fry crisp, damp ones sulk.
- 3
Fry until crisp
Heat the frying oil in a deep pan to 170C. Fry the potatoes in small batches, stirring gently at first so they don't clump, until pale golden and crisp, 5 to 7 minutes per batch. Lift them out with a spider or slotted spoon and drain on a rack or paper. Salt lightly while still warm.
Do not crowd the pan. If the oil temperature drops too far, the potatoes absorb oil before they crisp, and the final sauce will make them heavy. - 4
Start the sauce
Warm 3 tablespoons oil in a wide frying pan over medium heat. Add the shallots and cook until soft and lightly golden, then add the garlic and sliced chilies for another minute. The garlic should smell sweet and sharp, not brown and bitter.
- 5
Make the lacquer
Stir in the sambal oelek, ketjap manis, tamarind paste, sugar, torn lime leaves, and salt. Cook for 2 to 3 minutes, stirring, until the sauce thickens, darkens, and leaves a glossy trail when you drag the spoon through the pan. Taste it now: it should be hot, sweet, salty, and sour in one small argument.
- 6
Coat and serve
Turn the heat low and add the fried potatoes. Toss quickly and gently until the matchsticks are thinly coated, then take the pan off the heat at once. You want a lacquer, not a bath. Scatter fried shallots over the top if using, and serve warm or at room temperature beside rice, chicken, eggs, or a proper rijsttafel spread.
Chef Tips
- •Use waxy potatoes, not floury ones. Floury potatoes break into crumbs before they become matchsticks, and crumbs drink sauce like gossip drinks coffee.
- •Ketjap manis is not ordinary soy sauce. It is sweet, dark, and thick, with palm sugar in its bones. If you must substitute, mix 1 tablespoon dark soy sauce with 1 tablespoon dark brown sugar, but know what you've traded away.
- •For a party, fry the potatoes earlier in the day and keep them uncovered at room temperature. Toss with the sauce shortly before serving so they keep their bite.
- •If you like it hotter, add more sambal oelek to the sauce rather than extra fresh chili at the end. The chili needs a minute in oil to lose its raw edge.
Advance Preparation
- •The potatoes can be cut up to 4 hours ahead and held in cold water; drain and dry them thoroughly before frying.
- •The potatoes can be fried up to 8 hours ahead and kept uncovered at room temperature. Coat them with the sauce just before serving.
- •Leftovers keep 2 days refrigerated, but they lose their crispness. Rewarm them in a dry frying pan, not the microwave.

Bawang Goreng (Crisp Fried Shallots)
Bawang goreng means fried onion, but on the Indo-Dutch table it is far more precise: the crisp golden shallot that makes nasi, soto, and sajoer taste finished.

Emping Melinjo
The connoisseur's cracker of the Indo-Dutch table: bitter, crisp, pounded from melinjo seeds, and fried so quickly that hesitation is the only real danger.

Gado-gado with Warm Pindasaus
The name means a jumble, and the plate proves it: green beans, cabbage, egg, potatoes, and tofu gathered under pindasaus, Java carried into the Dutch rijsttafel.
