I was too young to eat this when my mother and aunties made it at my grandmother's house. I watched them char the vegetables over the charcoal grill, the green chilies and shallots blistering and blackening, the smoky smell rising and carrying across the yard, and I understood that something important was happening even before I understood what it was. As an adult I finally tasted it and understood completely. This was the sauce that sat quietly alongside everything else and made it all more itself. That is still exactly what it is. Make it. Put it in the center of the table. Watch what it does to everything around it.
Roast the VegetablesTo prepare the roasted green chilies, garlic, and shallots, preheat your oven to 400°F (200°C). Place the green chilies, garlic cloves, and shallots on a baking sheet lined with parchment paper. Leave the skins on the garlic cloves to protect them from burning. Roast the vegetables for 20-25 minutes or until the chilies have charred skins, and the shallots and garlic are soft and caramelized. This roasting process will enhance the flavors of the vegetables and add a delightful smokiness to your dish.
Peel and PrepOnce the vegetables are roasted, it is essential to allow them to cool down to room temperature. Next, peel the garlic and shallots, and carefully remove the skins from the chilies to prepare them for further use.
Mash the IngredientsFollowing the roasting of the chilies, garlic, and shallots, Use the mortar and pestle or food processer to mix the ingredients until they form a coarse paste.
Season the DipTransfer the mashed mixture to a bowl, gently stir in the fish sauce, freshly squeezed lime juice, and finely chopped cilantro. Then, carefully season the mixture with salt according to your taste preferences.
ServeThai Chili Sauce is best enjoyed with fresh, crisp vegetables such as cucumbers, carrots, and cabbage. It also pairs perfectly with warm, sticky rice, allowing you to savor the spicy flavors. Furthermore, it can be used as a delectable condiment to elevate the taste of grilled meats, adding flavor to each bite.
Notes
The charring must be genuine. Not softened, not lightly browned, genuinely charred, the skins blackened and blistered, the flesh inside soft and smoky. The charring is where the entire character of this sauce is built. Vegetables that are only partially charred produce a sauce that tastes like roasted vegetables with chili. Vegetables that are fully charred produce Nam Phrik Num, deep, smoky, complex, the kind of thing that makes people ask what is in it. Give the charring stage the time it needs. Five to eight minutes over direct heat. More if needed. The color of the skin will tell you when it is ready.Do not rinse the charred vegetables under water. The char that clings to the flesh after peeling is part of the flavor, it is the smoky quality that makes this sauce what it is. Rinse it away and you are rinsing away the whole point of the charring step. Peel the skin off dry. Accept the slightly blackened flesh. That blackening is correct.The texture should be rough. A smooth Nam Phrik Num is not Nam Phrik Num,it is a blended green chili paste. The mortar produces the right texture: rough, chunky, with visible pieces distributed through the sauce. Stop pounding before it becomes smooth. The rough texture is what allows the sauce to cling to sticky rice and vegetables in the way it should.Taste the sauce before it goes to the table and taste it again after it has sat for ten minutes, the flavors settle and integrate as the sauce rests, and what seemed slightly sharp right after pounding often rounds beautifully after a short rest. Make it at least fifteen minutes before serving. It improves with a little time.
