Chef-tested recipe
Brunei’s iconic sago-starch staple, stirred until glossy and elastic and eaten by twirling it onto sticks before dipping it into sharp, savory cacah.

Ambuyat is deeply associated with Bruneian food culture. Its flavor is mild; the pleasure comes from its distinctive texture and the contrast of strongly flavored dipping sauces and side dishes. Cacah varies by family and season, often using sour fruit, chilli and shrimp paste.

Ingredients
- Ambuyat
- 300 g ambulong or high-quality sago starchpaid link
- 650 ml freshly boiling water, approximately
- 100 ml room-temperature water
- Sour cacah
- 120 g very sour green mango or binjai flesh when available
- 15 g shrimp paste, lightly toasted
- 4 bird’s-eye chillies
- 20 g shallot
- 10 g sugarpaid link
- 3 g fine saltpaid link
- 80 ml warm water
Preparation Overview
Moisten the starch first, then beat in boiling water until it changes from opaque white to translucent, glossy and stretchy. Prepare the cacah separately and serve both immediately with vegetables, fish or meat side dishes.
Method
-
Mash the sour fruit, toasted shrimp paste, chillies, shallot, sugar and salt. Stir in warm water until the cacah is spoonable but still intense. Set aside.
-
Place sago starch in a heatproof bowl. Stir in 100 ml room-temperature water to make an even white slurry.
-
Bring 650 ml water to a full rolling boil.
-
Pour about two-thirds of the boiling water into the starch while stirring vigorously with a sturdy wooden spoon.
-
Continue beating. Add more boiling water little by little until the mixture becomes translucent, glossy and elastic. It should pull into long strands rather than remain chalky.
-
Serve immediately. Use candas or chopsticks to twirl a bite of ambuyat, dip it into cacah and eat without chewing heavily.
Beginner Technique Notes
- The water must be fully boiling to gelatinize the starch correctly.
- Add the last portion of water gradually; different starches absorb slightly different amounts.
- If the ambuyat remains milky and breaks instead of stretching, it needs more heat or boiling water.
Tips and Variations
- Binjai gives a distinctly local sour-fruit character when available; green mango is an accessible substitute.
- Cacah can also be made with tempoyak or other sour local ingredients depending on family tradition.
- Keep accompanying dishes strongly seasoned because ambuyat itself is intentionally neutral.
Storage
Ambuyat is best made immediately before eating. It firms and loses its ideal stretch as it cools. The cacah can be refrigerated for up to 2 days.
Nutritional Value
Approximately 290 kcal per serving from the ambuyat and cacah, excluding side dishes.
Allergen Notes
Contains crustaceans through shrimp paste. Sago starch itself is naturally gluten-free.
