Malaysian sambal tumis is a cooked chili condiment made with dried red chilies, shallots, garlic, tamarind, and often belacan, or fermented shrimp paste. Gently frying the chili paste builds a rounded, savory flavor that works alongside rice, noodles, vegetables, and many other meals; versions vary by region and household.
Ingredients
- 1½ ounces (42 g) dried red chilies, stems removed and chilies cut into pieces. These provide the main heat and color; use a milder variety or remove the seeds for a gentler sambal.
- 2 cups (480 ml) just-boiled water, for soaking the dried chilies. You will drain and discard this water.
- 1 cup (150 g) peeled shallots, roughly chopped. Shallots add sweetness and body; if unavailable, use an equal weight of yellow onion, which tastes a little sharper.
- 3 garlic cloves (about 15 g), peeled. Garlic supports the chili and shallot flavors without taking over.
- ¼ cup (60 ml) water, for blending the paste. Add it gradually so the mixture blends without becoming unnecessarily thin.
- 1 teaspoon (5 g) belacan, crumbled. This Malaysian fermented shrimp paste adds a distinctive savory depth. It is optional; for a seafood-free version, leave it out and season to taste with a little more salt.
- ⅓ cup (80 ml) neutral cooking oil, such as canola or sunflower oil. The oil helps the paste fry evenly and makes the finished sambal easier to spoon.
- 1 tablespoon (15 g) tamarind paste, mixed with ¼ cup (60 ml) warm water. Tamarind gives the sambal a tart counterpoint to the chilies and sugar.
- 1 tablespoon (12 g) palm sugar or light brown sugar. Palm sugar is traditional in many versions; light brown sugar is a practical substitute with a slightly less caramel-like flavor.
- ¾ teaspoon (4 g) fine salt, plus more to taste. If you omit the belacan, start with the listed amount and adjust after the sambal simmers.
Instructions
- Soak the chilies for 15 minutes. Place the cut dried chilies in a heatproof bowl and cover them with the just-boiled water. Let them soften while you chop the shallots and prepare the other ingredients. Drain well after soaking and discard the soaking water. Soft chilies blend more easily and are less likely to leave tough flecks in the sauce.
- Blend the chili paste. Put the drained chilies, shallots, garlic, and ¼ cup (60 ml) water in a blender or food processor. Blend until mostly smooth, stopping to scrape down the sides as needed. A little texture is fine, but aim for a cohesive paste with no large pieces of dried chili. If your machine struggles, add water 1 tablespoon (15 ml) at a time rather than pouring in extra all at once.
- Toast the belacan, if using. Set a wide, heavy skillet or sauté pan over medium heat. Add the belacan and stir it for about 1 minute, just until fragrant, then transfer it to a small dish. Keep the pan ventilated; fermented shrimp paste has a strong aroma. If your belacan is already toasted, you can skip this step and crumble it into the paste later.
- Fry the paste for 25 minutes. Add the oil to the pan and warm it over medium-low heat. Stir in the blended paste and toasted belacan. Cook for 25 minutes, stirring often and scraping the bottom and corners so the paste does not catch. Lower the heat if you see dark spots forming quickly. The paste should become a deeper red, lose its raw, sharp smell, and look thicker; small beads or a thin sheen of oil may appear around the edges.
- Add the tamarind and seasonings. Stir the tamarind paste into its warm water until combined, then pour it into the pan. Add the sugar and salt. Mix thoroughly, scraping the base of the pan to loosen any browned paste. The mixture may loosen at first; that is expected as the liquid combines with the fried chili paste.
- Simmer for 9 minutes and taste. Keep the pan at a gentle simmer, stirring frequently, until the sambal is glossy and thick enough to mound briefly on a spoon. Taste a small amount after it cools slightly. Add salt if it tastes flat, sugar if the acidity feels too sharp, or a teaspoon of water if it is thicker than you want. Remove from the heat and let it cool before serving or packing away.
Tips
- Choose your heat level before blending. Dried chilies vary considerably in size and heat, and removing seeds can make a noticeable difference. For a milder batch, open the chilies and shake or scrape out some seeds before soaking. If you want more heat, keep the seeds or blend in a small fresh red chili, understanding that it will add a brighter, fresher flavor.
- Use a pan with room to stir. A wide skillet lets moisture escape and helps the paste fry rather than steam. A narrow saucepan can still work, but the paste will be deeper and may need closer attention. Stir and scrape regularly, especially once the mixture thickens; scorched paste can make the whole batch taste bitter.
- Let color and aroma guide you, not just the clock. The goal is to cook away the raw smell and deepen the chili color without burning the shallots. If the paste is still watery at the end of the timed fry, keep it over low heat and stir until thicker; if it darkens too quickly, reduce the heat. The amount of water retained during blending and the pan size affect how fast it cooks.
- Adjust in small increments. Tamarind pastes differ in strength, and chili batches differ in heat. Make small changes after the simmer rather than adding a large amount of sugar, salt, or tamarind at once. The flavor should be chili-forward, savory, slightly sweet, and tangy, not sugary or sharply sour.
Serving Suggestions
Serve sambal tumis as a condiment, not as a mild dipping sauce: a spoonful gives a plate a concentrated mix of heat, sweetness, acidity, and savory flavor. Start with about 1 teaspoon per serving, then let everyone add more. It is especially good with plain steamed rice, coconut rice, or rice bowls, where the grains soften the chili’s intensity and soak up the glossy sauce.
Try it beside stir-fried greens, roasted vegetables, grilled tofu, or simply cooked noodles. You can also stir a spoonful into fried rice near the end of cooking, spread a thin layer inside a sandwich, or mix it with a little warm water and lime juice for a looser dressing. For a composed meal, pair it with a mild vegetable dish and a plain starch so the sambal remains the most assertive flavor. Avoid adding a large amount to a whole pot before tasting: the heat can build quickly, and diners may prefer different levels.
Variations
Less spicy sambal: Before soaking, remove the seeds and pale inner membranes from the dried chilies. You can also replace up to one-third of the dried chilies with mild dried red peppers. The color and chili flavor will remain, but the finished condiment will have less heat.
Without belacan: Omit the shrimp paste for a seafood-free version. The result will be less fermented and savory, so taste after simmering and add a pinch of salt if needed. Do not substitute fish sauce in equal quantity; it is much saltier and more liquid, and it will change both the seasoning and texture.
More tangy or more mellow: For a sharper finish, add another teaspoon (5 g) of tamarind paste dissolved in water, then simmer briefly and taste again. For a rounder sambal, add up to 1 teaspoon (4 g) more sugar. These are small adjustments, not a requirement: the balance depends on the particular chilies and tamarind you use.
Fresh-chili variation: Blend in one or two fresh red chilies with the soaked dried chilies. Fresh chilies lend a brighter, greener edge, while dried chilies provide the deeper, concentrated flavor associated with this cooked style. Keep the total amount modest until you know the heat of your fresh peppers.
Storage and Reheating
Cool the sambal promptly and refrigerate it within 2 hours of cooking. Store it in a clean, covered container in the refrigerator for 3 to 4 days. Use a clean spoon each time you serve it, and do not leave the container sitting out through a long meal. For longer storage, freeze in small portions for up to 2 to 3 months for best quality; thaw a portion in the refrigerator before using. Refrigerate or freeze the sambal rather than storing it at room temperature.
To serve it cold or at room temperature, you can spoon it straight from the refrigerator and let the portion stand briefly while you prepare the meal. To warm it, heat only what you need in a small skillet over low heat, stirring until hot, or microwave it in a covered microwave-safe dish in short intervals. USDA FSIS recommends reheating leftovers to 165°F (74°C); use a food thermometer to check the center of a larger portion. Add a teaspoon of water if the sauce has thickened in the refrigerator, and stir it in well.
Frequently Asked Questions
Is Malaysian sambal always made with belacan?
No. Belacan is common in many Malaysian sambal recipes, but ingredients and proportions vary. It gives this version a deep, fermented savory note. You can leave it out if you do not eat shrimp or cannot find it; the sauce will still be a useful chili condiment, though it will taste less savory and rounded.
Can I use fresh chilies instead of dried chilies?
You can make a fresh-chili variation, but it will taste different. Dried chilies bring concentrated flavor and a darker color, while fresh ones taste brighter and contain more moisture. For the closest result, keep the dried chilies as the base and blend in a small amount of fresh red chili rather than replacing all of them.
Why does my sambal taste bitter?
The most common cause is paste that has scorched on the bottom of the pan. Use medium-low heat, stir frequently, and reduce the heat as the paste thickens. Some dried chilies can also have a slightly bitter edge, especially if their seeds are very dark or damaged. A little sugar may soften bitterness, but it will not fix a strongly burnt batch.
Why is oil separating from the sambal?
A slight sheen or small beads of oil around the edges are normal signs that the paste has fried and thickened. A large pool of oil is not necessary for serving. If there is more than you prefer, spoon some off once the sambal is cooked, or stir the sauce before serving to redistribute a small amount.
Can I make the sambal less salty or sweet?
Yes. Start with a little less salt or sugar, then taste after the tamarind has simmered into the paste. Belacan contributes saltiness, so omitting it may mean you need to add a little more salt, while the strength of the tamarind affects how sweet the sambal seems. Adjust gradually, because the flavors become more concentrated as the sauce cools.
