1-First Step: Get everything ready Start by washing the red jalapeños and red bird’s eye chillies well. Pat them dry, then slice them if you want the paste to come together faster. If you are using a mortar and pestle, have it ready on the counter. If you are using a chopper, make sure it is clean and dry. Dry-roast the shrimp paste in a pan first if it has not already been toasted. This step helps deepen the flavor and takes away some of the raw sharpness. Keep the heat medium and move it around so it does not burn. Once it smells fragrant, it is ready to use.

2-Second Step: Pound the chilies Add the chilies, white sugar, and salt to the pestle and mortar. Pound them until the mixture looks semi-coarse. You do not need a smooth paste at this point. The goal is to break down the chilies while keeping some texture, which gives Malaysian Sambal Belacan a more traditional feel. If you like less heat, you can remove some seeds before pounding. That is a good trick for home cooks who want a milder version. You can also use more jalapeños and fewer bird’s eye chillies if you are cooking for children, seniors, or anyone sensitive to spice.

3-Third Step: Add the belacan Next, add the toasted shrimp paste, also known as belacan. Pound it for about a minute so it blends into the chilies. The paste should start to smell savory and rich. This is the point where the mixture becomes the classic Malaysian Sambal Belacan base. Belacan has a strong flavor, so add it slowly if you are new to it. Some cooks like a stronger seafood note, while others prefer a lighter touch. If you are making this for the first time, keep the full tablespoon as written, then adjust next time based on your taste.

4-Fourth Step: Mix in lime juice and zest Squeeze in the juice of 1 Persian-type lime or 2 calamansi, then mix well. If you want extra brightness, add the zest of 1 lime. The citrus cuts through the saltiness of the shrimp paste and rounds out the heat from the chilies. This tangy finish is one reason Malaysian Sambal Belacan tastes so lively. The lime juice also helps the paste feel fresher when served with plain rice or rich dishes. Stir it until everything looks evenly mixed and glossy.

5-Fifth Step: Use a chopper if you want a quicker version If you do not have a pestle and mortar, place all ingredients in a chopper and process until the mix looks smooth-ish. It will be a little more even in texture and still taste great. Traditional pounding gives a better bite, but a food processor is very practical on busy days. This is a great option for students, working professionals, or anyone who wants a fast homemade condiment. The flavor stays bold, and cleanup is usually easier too.

6-Final Step: Taste, store, and serve Taste the sambal belacan and adjust if needed. Add a little more lime juice for brightness, a bit more sugar for balance, or more chili if you want extra heat. Once it tastes right, spoon it into a clean jar and store it in the fridge for up to 2 weeks. Serve it with rice, noodles, grilled fish, fried eggs, fresh cucumber, or even simple steamed vegetables. A small spoonful goes a long way, so start with less and add more as needed.
