Chef John's Thai-Style Sweet Chili Sauce

Step 1

Place 1/2 cup cold fresh water and vinegar in a saucepan. Whisk in Asian fish sauce, brown sugar, ketchup, sambal chili sauce, and cornstarch. Whisk until cornstarch disappears. Place over medium-high heat and bring up to a simmer stirring occasionally. As it bubbles, it will start to thicken up. Remove pan from heat.

Step 2

Whisk garlic and chili into hot mixture. Add fresh lime juice; whisk again. Allow mixture to cool to room temperature before checking for seasonings.

Step 3

If not using immediately, transfer to a glass jar with a lid. Refrigerate.
