Ingredients

• 1.5 oz (about 40-55g) dried red chiles (such as guajillo, chile de árbol, or a blend of dried Asian red chiles), stems removed
• 1 medium yellow onion (about 6 oz / 170g), roughly chopped, or 3-4 shallots
• 6-8 cloves garlic (about 1 oz / 28g), peeled
• ½ cup (120 ml) neutral oil (like vegetable, canola, or grapeseed), plus extra for topping if desired
• 1-2 tablespoons (15-30g) brown sugar or palm sugar, to taste
• 1 tablespoon tamarind concentrate (or 2 tablespoons fresh lime juice)
• 1 teaspoon (5g) salt, or to taste
• ½ teaspoon belacan (dried shrimp paste), optional (small piece, about 2-3g)

Directions

1. Prep Chiles Safely: Rinse the dried chiles thoroughly under cool water. Place them in a heatproof bowl and cover with boiling water. Let them soak for 15-20 minutes until softened. Once soft, drain the chiles. For a milder sauce, you can optionally slice them open and remove some or all of the seeds.
2. Blend the Paste: Combine the soaked chiles, chopped onion, garlic, and optional belacan (shrimp paste) in a blender or food processor. Add just enough of the neutral oil (start with ¼ cup) to help the blades move, blending until you achieve a coarse, rustic paste. Avoid making it too smooth; a little texture is good.
3. Cook It Down (This is the Whole Game): Heat the remaining ¼ cup of neutral oil in a wok or large skillet over medium-low heat. Add the blended chili paste carefully (it will splatter!). Stir constantly to prevent sticking and burning. Cook for 30-40 minutes, or until the paste darkens in color, thickens considerably, and the oil separates and turns a vibrant red, rising to the surface. This slow cooking process is crucial for developing deep flavor and ensuring a longer shelf life.
4. Season and Balance: Stir in the brown sugar (or palm sugar), tamarind concentrate (or lime juice), and salt. Continue to cook for another 5 minutes, stirring, allowing the flavors to meld. Taste and adjust seasoning as needed – add more sugar for sweetness, more acid for tang, or more salt for balance. Remember to add in tiny increments!
5. Cool and Jar: Remove the sambal from the heat and let it cool completely to room temperature. Transfer the cooled sambal into a clean, airtight jar. For extra preservation, you can pour a thin layer of neutral oil over the top before sealing.
