Sambal Matah
Sambal Matah · A raw, uncooked Balinese condiment composed of very finely minced shallots, lemongrass, bird's eye chilies, kaffir lime leaves, and galangal, emulsified with coconut oil and brightened with lime juice. The name means 'raw sambal' in Balinese. Unlike cooked sambals, matah is never heated, relying entirely on fresh, aggressive aromatics and the emulsifying action of coconut oil to create a cohesive, punchy sauce.
The formula
100:30:12:5:30 — shallots : oil : chilies : galangal : lime juice
All ingredients finely minced. Scales linearly: multiply or divide all weights proportionally. At 100g shallots the yield is approximately 180g finished sauce, enough for 4–6 servings as a finishing sauce. For a milder version reduce chilies to 2; for extra punch add 1 extra stalk lemongrass. The oil weight is approximate — enough to coat all solids in a glistening, not greasy, layer.
Identity
- A completely raw preparation — nothing is cooked or heated at any point
- Coconut oil as the sole binding and emulsifying medium, not water-based
- Shallots as the structural base, not onions or shallot powder
- Kaffir lime leaves and galangal as defining aromatics that distinguish it from other raw sambals
Ingredients
| Base | Shallots | The structural foundation. Peel and very finely mince to 2–3mm. Red shallots preferred for color. Approximately 100g yields ~5–6 medium shallots. |
| Base | Lemongrass | Use only the white and pale green lower portions. Remove tough outer layers and slice paper-thin, then mince. The upper stalk is fibrous and unpleasant. Approximately 2 medium stalks per 100g shallots. |
| Aromatics | Bird's eye chilies (cili padi) | The characteristic heat. Remove stems; leave seeds in for maximum punch. Roughly chop before mincing. Amount is flexible — 4 provides noticeable heat; 8 is aggressively hot. Thai chilies are an acceptable substitute. |
| Aromatics | Kaffir lime leaves | Stack 4–6 leaves, roll tightly, and slice into very thin ribbons (chiffonade), then roughly chop. The citrus-pine note is essential and irreplaceable. Do not substitute with lime zest or Western bay leaves. |
| Aromatics | Galangal | Use a thin slice (5–8g), minced extremely fine. Galangal is more citrusy and less medicinal than ginger. Traditional in many Balinese versions. If unavailable, use slightly more fresh ginger as a poor substitute. |
| Acid | Lime juice | Freshly squeezed only. Juice of 1 large or 2 small limes (~30g). The acid brightens the aromatics and helps the oil adhere. Calamansi is an acceptable regional substitute. |
| Fat | Coconut oil | Refined coconut oil preferred for neutral flavor; extra-virgin coconut oil adds coconutty intensity. This is the emulsifier and binder — it carries the oil-soluble aromatic compounds from the lemongrass and kaffir lime. Use enough to coat all solids in a glistening film. |
| Seasoning | Fine sea salt | Start with 3g per 100g shallots; taste and adjust. Salt is not optional — it suppresses the raw sharpness of the shallots and integrates the flavors. |
Method
- 1Prepare all aromatics in advance and have them ready before combining. Peel and mince the shallots to a 2–3mm dice or smaller. Slice the lemongrass white/pale parts paper-thin, then mince. Remove stems from chilies and roughly chop. Stack, roll, and thinly slice kaffir lime leaves into ribbons, then chop. Peel and mince the galangal slice to a fine paste. Juice the lime.Everything is raw and there is no cooking step to develop flavors. Each ingredient must be prepared uniformly and small enough to distribute evenly. The lime juice is the last liquid to be added, so it must be ready.
- 2Combine the minced shallots, lemongrass, chilies, kaffir lime leaves, and galangal in a non-reactive bowl. Add salt and toss to distribute evenly. Allow to rest for 2 minutes.Salt begins to draw out moisture from the shallots, creating a slight brine that helps the oil adhere and reducing the raw, sulfurous edge. A brief rest also allows the salt to begin penetrating the cell walls of the aromatics.
- 3Pour the coconut oil over the aromatic mixture. Using a fork or small spatula, toss and fold the ingredients while slowly drizzling in the oil, ensuring all pieces are coated in a thin, glistening film.The oil is the sole binding medium. Tossing slowly incorporates air and ensures even distribution. The oil must coat every piece to create a cohesive sauce that clings to food rather than pooling at the bottom of the bowl.
- 4Add the lime juice and toss again to combine. Taste immediately for seasoning.The acid is added last to preserve its fresh, bright character. It should not be cooked or even briefly heated, or it dulls. Taste and adjust salt, heat, or acid as needed.
- 5Serve immediately at room temperature, or refrigerate for up to 4 hours. If refrigerating, return to room temperature for 15 minutes before serving — the oil will solidify when cold, which dulls the aroma release.Sambal matah is a volatile, fresh sauce. The aromatics are most aromatic immediately after preparation. At room temperature, the fat releases the volatile compounds from the lemongrass and kaffir lime efficiently, maximizing aroma impact on the palate.
Techniques that matter
Fine mincing (brunoise)
All ingredients are raw and never cooked. Uniform, small pieces (2–3mm) ensure the sauce is cohesive rather than a pile of uneven fragments. Larger pieces would be texturally jarring and would not distribute evenly through the oil.
Oil-based emulsification (passive)
Unlike a vinaigrette which requires vigorous whisking, this sauce relies on the oil naturally coating the minced aromatics in a thin film. The moisture drawn from the shallots by salt creates enough of a hydrophilic phase that the oil disperses without mechanical emulsion — hence 'passive' emulsification.
Balancing pungency with salt and acid
Raw shallots and chilies can be aggressively sharp and one-dimensional without intervention. Salt tames the sulfurous compounds; lime acid provides brightness and balance. This is the same principle as seasoning any raw allium preparation, but here it is the entire flavor architecture.
Variations & derivatives
Sambal Matah with TerasiBali, Indonesia
Add a small amount (2–3g) of toasted, ground dried shrimp paste (terasi) dissolved into the lime juice. Adds umami depth and a fermented, seafood backbone. Common in inland Balinese versions.
Sambal Matah SeleraMalaysia
Malaysian adaptation often adds a teaspoon of toasted belacan (shrimp paste) and sometimes a touch of palm sugar. Slightly more complex and less purely fresh than the Balinese original.
Sambal Matah with Coconut CreamJava, Indonesia
Substitute part of the coconut oil with thick coconut cream (santan). Creates a richer, more unctuous sauce with additional coconut sweetness. Popular in Javanese renditions.
Sambal Matah PedasBali, Indonesia
Doubles or triples the chilies for an extra-hot version. Often served alongside milder grilled fish or chicken where the sauce is the primary seasoning agent.

Substitutions
- Bird's eye chilies → Thai chilies or serranos — Serranos are slightly milder and less fruity but acceptable. Do not substitute with jalapeños (too mild and watery) or dried chilies (entirely different character).
- Kaffir lime leaves → Lime zest + a pinch of citrus oil — A compromise: zest adds citrus note but lacks the piney, floral quality. Use sparingly — zest can be overpowering. Not fully safe; the character changes significantly.changes result
- Galangal → Fresh ginger (50% more) — Ginger is more medicinal and spicy than galangal's floral-citrus note. Use only in emergencies. The result is recognizably related but distinctly different.changes result
- Shallots → Spring onions (scallions) + red onion — In a pinch, use the white parts of 4 scallions minced fine plus 1/4 small red onion for color and mild allium base. Not traditional but functional. Significantly changes the texture and sharpness.changes result
- Coconut oil → Neutral vegetable oil — Works technically but loses the coconut aroma that is integral to the sauce's identity. Use only if coconut oil is genuinely unavailable and you accept the flavor loss.changes result
Troubleshooting
The sauce tastes overly harsh, sharp, or sulfurous
Insufficient salt, too little acid, or shallots were not minced finely enough. Large allium cells rupture on the palate rather than dispersing, producing an aggressive raw-onion sensation. → Add salt incrementally, tasting after each addition (up to 50% more than initially used). Add more lime juice. If the shallot pieces are large, remix with additional very finely minced shallot to dilute the large pieces.
Oil separates and pools at the bottom of the bowl
Not enough oil to coat all solids, or insufficient moisture drawn from the shallots to create a hydrophilic phase. Occurs when shallots are particularly dry or the oil is too cold and viscous. → Add coconut oil 1 teaspoon at a time, tossing, until the solids are fully coated. If the oil has solidified (cold environment), let the bowl sit at room temperature for 10 minutes before reassessing.
The aromatics (lemongrass, kaffir lime) taste fibrous or unpleasant
Using the tough upper portion of the lemongrass stalk, or failing to mince the kaffir lime leaves finely enough. These aromatics must be gelatinously fine to be palatable raw. → Use only the white and pale green lower third of lemongrass stalks. Re-prep kaffir lime leaves, stacking them tightly and cutting into a very fine chiffonade, then mincing. Discard any fibrous material.
Flavor is flat and lacks punch after refrigeration
Refrigerating dulls volatile aroma compounds, especially from the kaffir lime and lemongrass. The coconut oil solidifies, further suppressing release. Prolonged cold storage is the enemy of this sauce. → Use immediately or within 4 hours of refrigeration. Bring to room temperature for at least 15 minutes. Accept that freshly made is always superior; this sauce is not suited to long storage.
