Thai Sweet Chili Sauce

Sweet chili sauce (nam chim kai) is a classic condiment served with southeast Asian cuisine, especially in Thailand. Itcan be used as a dipping sauce, a marinade, a glaze, and more. It’s my go-to for spring rolls, but I also use it to jazz up fried tofu! Honestly, it’s good on EVERYTHING!

Is Sweet Chili Sauce the Same as Sweet and Sour Sauce?

Though they are similar in purpose as a dipping sauce and marinade, sweet and sour sauce and sweet chili sauce have different ingredients and flavor profiles.

Sweet and sour sauce is pineapple-based, with no heat (spice). It is naturally brown in color, and red food coloring is added to give it the distinctive color you might be used to seeing in restaurants or in bottles at the store.

Sweet chili sauce, on the other hand, incorporates red chilis and does have hint of spice. How spicy depends on how much and what type of pepper is used. It also contains a fair amount of sugar, which tones down the heat.

As a kid, I loved sweet and sour sauce. As a grown-up, I appreciate a bit of spice! Sweet chili sauce is one of my favorite condiments and I always keep some on hand.

Ingredients

• 1/2 cup rice vinegar
• 1/2 cup water
• 1 cup sugar
• 1 tablespoon garlic, minced
• 1 tablespoon light soy sauce (use coconut aminos for GF version)
• 4 teaspoons red pepper flakes or red chili flakes

for the Corn-starch slurry

• 3 teaspoons cornstarch
• 2 tablespoons water

Instructions

In a small bowl, whisk together the corn starch and water to form a slurry; set aside.

1. Toast the red chili flakes in a medium saucepan on the stovetop for about 3 minutes over medium heat. This helps to develop the flavors of the spice.
2. Add your vinegar, water, sugar, minced garlic, and soy sauce and bring this mixture to a boil. Allow to boil for 4 minutes, stirring as needed to keep from boiling over.
3. Reduce heat to low. Slowly add the cornstarch slurry, whisking until fully incorporated.
4. Remove pan from heat. The sauce is ready to use right away, but it will continue to thicken as it cools.Allow sauce to cool to room temperature before transferring to an airtight container and storing.

Frequently Asked Questions

Does this Sweet Chili Sauce Need to Be Refrigerated?

Yes, your homemade sweet chili sauce needs to be kept refrigerated. It is made without added preservatives like you’d find in a store-bought bottle, however, the high vinegar content does help it keep longer than most homemade sauces. When stored in a glass jar or food storage container in the refrigerator, your sweet chili sauce should stay good up to a month.

Are Red Pepper Flakes and Red Chili Flakes the Same Thing?

Red pepper flakes and red chili flakes are essentially the same thing and can be used interchangeably. The main difference is the type of pepper used: chili flakes are made from red chili peppers, while red pepper flakes can be made from a combination of peppers.

Since they can be made from a variety of peppers, the red pepper flakes have potential for being spicer. If you’re new to spice, I recommend sticking with red chili flakes, which are more predictable. You could also look for red pepper flakes that are labeled as mild.

On the other hand, if you want a spicier sauce, use red pepper flakes labeled as hot. Trying different varieties of peppers allows you to experiment with spice levels.

Is Sweet Chili Sauce Gluten Free?

Since soy sauce contains wheat ingredients, the original recipe is not entirely gluten free. However, this can easily be converted into a gluten-free recipe by substituting coconut aminos for the light soy sauce. The flavor will be almost exactly the same!
