Bowl filled with Sweet Thai Chili Sauce

Thai Sweet Chili Sauce (Nam Jim Gai)

Susie Thompson
When we were at my grandmother's farm, my aunties made this sauce and even as a young child I watched them. I did not yet know what it was or why everyone reached for it first, but I could see that they did. Sweet and bright and just spicy enough, going on everything that came off the grill. The question was never whether to use it. The question was how much. I still make this the same way and it is still always the first thing gone. Make a jar this week and put it in your refrigerator. You will find reasons to use it every single day.

Ingredients
  

  • 1 cup rice vinegar
  • 1 cup sugar
  • 1/2 cup water
  • 2 tablespoons fish sauce
  • 1 tablespoon minced garlic
  • 2 teaspoons red chili flakes or 2-4 fresh chili-chopped
  • One tablespoon cornstarch
  • 2 tablespoons cold water

Instructions
 

  • Combine the white sugar, rice vinegar, and water in a medium saucepan over medium heat. Stir continuously until the sugar completely dissolves, creating a smooth, syrupy base for your sauce.
  • Add the minced garlic and finely chopped chili peppers to the pan. Allow the mixture to simmer gently for 5-7 minutes, stirring occasionally. This step allows the flavors of the garlic and chili peppers to infuse into the sauce, creating a robust and aromatic blend.
  • Mix the cornstarch slurry with water until it is fully dissolved and smooth. This slurry will thicken the sauce to the desired consistency and ensure it coats your dishes beautifully.
  • Pour the cornstarch mixture into the saucepan, stirring constantly. Continue cooking for 2-3 minutes until the sauce thickens to a glossy, velvety texture. Remove the saucepan from the heat and let the sauce cool to room temperature.
  • Once cooled, carefully transfer the  Sweet Thai Chili Sauce into a clean, airtight jar or bottle for storage. Refrigerate until ready to use. Serve the sauce chilled or at room temperature, allowing its vibrant flavors to enhance your favorite dishes. Enjoy the authentic taste of Nam Jim Gai!

Notes

Fresh chilies produce a better sauce than dried chili flakes or chili paste. The bright red color, the fresh heat, and the vibrant flavor of the finished sauce come from fresh red chilies blended with fresh garlic before cooking. Dried alternatives produce something darker and less bright in both color and flavor. Fresh red chilies are available at most grocery stores year-round. They are worth using.
Do not over-reduce the sauce. The sauce thickens as it cools, and a sauce that looks perfectly thick in the hot pan will be too thick once it reaches room temperature. Pull it off the heat when it is still slightly thinner than you want. Let it cool, taste it, and return it to low heat for a few more minutes if it needs more body. Patient cooling produces a better result than aggressive reducing.
Rice vinegar is worth using over white vinegar. The acidity of rice vinegar is gentler and more rounded than white vinegar, and it produces a sauce that is bright without being sharp. The difference is noticeable in the finished sauce. Rice vinegar is inexpensive and widely available. Use it.
The sauce improves overnight. Make it the day before you need it if you can. The flavors settle and integrate as the sauce sits in the refrigerator, and the version you open the next day will be more cohesive and more itself than the version you made the night before. My aunties always had a jar ready. That is still the right approach.
