- 1 cup white sugar: Adds the essential sweetness that balances the spiciness.
- 1 Tablespoon garlic, minced: Brings a savory depth to the sauce.

Step-by-Step Guide to Making Thai Sweet Chili Sauce
Making Thai Sweet Chili Sauce is straightforward and involves just a few key steps. Follow this guide to ensure your sauce turns out perfect every time.
1. Preparing the Cornstarch Slurry
Start by whisking together 3 teaspoons of cornstarch and 2 tablespoons of water in a small bowl to form a slurry. Set this aside. This mixture will be used later to thicken the sauce.
2. Toasting the Red Pepper Flakes
In a medium saucepan, toast 4 teaspoons of red chili flakes over medium heat for about 3 minutes. This step enhances the flavors of the chili flakes, giving your sauce a deeper, more complex flavor profile.
3. Combining and Cooking the Ingredients
Next, add 1/2 cup of rice vinegar, 1/2 cup of water, 1 cup of white sugar, 1 tablespoon of minced garlic, and 1 tablespoon of light soy sauce (or coconut aminos for a Gluten-Free version) to the saucepan. Bring the mixture to a boil, and let it cook for 4 minutes, stirring occasionally to prevent the mixture from boiling over.
4. Thickening the Sauce with Cornstarch
Once the mixture has boiled, reduce the heat to low. Slowly add the cornstarch slurry to the sauce, whisking constantly to ensure it’s fully incorporated without lumps. Continue to cook the sauce on low heat until it thickens to your desired consistency. Remember, the sauce will continue to thicken as it cools.
Remove the pan from heat and allow the sauce to cool to room temperature before transferring it to a storage container.
