My homemade Thai Sweet Chili Sauce is so much better than the store bought version! It's the perfect balance of spicy and sweet and easily customizable to your own preference! (Makes about 2 1/2 cups)
Add the sugar, salt, water and vinegar in a small saucepan. Heat over medium heat and stir until the sugar is dissolved and turn off the heat.
In a blender or food processor, add the red chilis, thai chilis, and garlic. Pulse until no large chunks are visible.
Add the chili garlic mixture to the saucepan. Heat over medium heat until the sauce has reduced by half.
Add the cornstarch slurry mixture and mix until thickened. Turn off the heat and let cool completely.
Notes
2 thai chilis creates a sauce with mild heat. Adjust to 1 thai chili if you are sensitive to spice or increase to 3-4 thai chilis if you want the sauce more spicy.Store in the fridge in an airtight container for up to 2 weeks.
