1-First step: Gather and prep everything Wash the chilies and dry them well. If you want a little less heat, you can remove some of the chili seeds, but keep in mind that the classic flavor of sambal belacan usually has a good amount of spice. Measure out the salt, sugar, toasted shrimp paste, lime juice, and optional lime zest so everything is ready before you start. Because this recipe moves quickly, it helps to line up your ingredients before you toast the belacan. That way, the paste goes together smoothly and the chilies stay fresh and bright.

2-Second step: Toast the shrimp paste Heat a dry pan over low to medium heat and toast the dry roasted shrimp paste for a short time until fragrant. This step is very important because belacan is sun-dried fermented shrimp, and toasting it brings out its savory depth while softening the raw, pungent edge. The aroma will become richer and nuttier as it warms. Be careful not to burn it. You only need enough heat to wake up the flavor. Once toasted, let it cool for a minute so it blends more easily with the chilies. Toasting the belacan is the difference between a flat sambal and one with deep, savory character.

3-Third step: Pound the chilies for a traditional texture If you are using a pestle and mortar, add the red jalapeños, bird’s eye chilies, sugar, and salt first. Pound them until the mixture becomes semi-coarse. This gives the sambal belacan its classic rustic texture and helps release the juices from the chilies. Once the chilies start to break down, add the toasted shrimp paste and pound for about one more minute. The belacan should blend into the chili mixture without disappearing completely. You want little bits of texture, not a totally smooth paste.

4-Fourth step: Add the lime Stir in the juice of 1 Persian-type lime or 2 small calamansi. If you want a brighter scent, add the optional zest of 1 lime too. The acid cuts through the salt and spice and gives the malay chili paste a fresh finish. Taste the paste now and adjust if needed. If you want it tangier, add a little more lime juice. If it feels too sharp, a tiny pinch more sugar can help bring things back into balance.

5-Fifth step: Blend if you want a smoother paste For a quicker method, place all of the ingredients in a food processor or chopper and blend to your desired texture. Some people like a smooth paste, while others prefer a semi-coarse texture with visible chili bits. Both versions are tasty, so choose the one that fits your meal and your schedule. This method is especially handy if you are making sambal belacan for a crowd, because it saves time and keeps your hands safer from chili oils. If you do blend, pulse in short bursts so you do not over-process the mixture into a watery sauce.

6-Final step: Jar, chill, and serve Spoon the sambal belacan into a clean jar and refrigerate it for up to two weeks. The flavor usually settles and tastes even better after a short rest in the fridge. Before serving, let it sit at room temperature for a few minutes so the flavors open up again. Serve it with steamed rice, noodles, grilled fish, eggs, stir-fries, or fresh vegetables. It also works beautifully as a little spicy spread for canapes when you want to surprise guests with something bold and flavorful.
