INGREDIENTS FOR THAI SWEET CHILI SAUCE

Base:

• Water – Forms the liquid base to dissolve the sugar and other ingredients.
• Rice vinegar – Provides tanginess with a mild, clean finish typical of Thai sauces.

Sweeteners:

• White sugar – Balances out the heat and vinegar for that signature sweet profile.
• Honey (optional) – Adds depth and a subtle floral sweetness.

Seasonings:

• Garlic – Adds bold, aromatic undertones.
• Red pepper flakes – Supplies a gentle heat that’s easy to adjust to your spice preference.
• Salt – Enhances all the other flavors.
• Soy sauce – Adds a hint of umami and savory richness.

Thickener:

• Cornstarch – Thickens the sauce to a glossy, clingy consistency.

HOW TO MAKE THAI SWEET CHILI SAUCE

1. In a small saucepan, combine water, vinegar, sugar, garlic, red pepper flakes, soy sauce, and salt. Stir well to dissolve the sugar.
2. Bring the mixture to a gentle boil over medium heat.
3. Reduce the heat to low and let the sauce simmer for 5–7 minutes until slightly reduced.
4. In a separate bowl, mix cornstarch with a little water to make a slurry.
5. Slowly stir the slurry into the simmering sauce.
6. Continue simmering for another 2–3 minutes until the sauce thickens to your desired consistency.
7. Let cool, then transfer to a sterilized jar or bottle. Store in the refrigerator for up to 2 weeks.

FOR GLUTEN-FREE THAI SWEET CHILI SAUCE:

Thai Sweet Chili Sauce can be gluten-free, but it depends on the specific ingredients you use—especially the soy sauce.

• Soy Sauce: Traditional soy sauce contains wheat. To keep the recipe gluten-free, use gluten-free tamari or gluten-free soy sauce.
• Other Ingredients: Vinegar, sugar, garlic, red pepper flakes, salt, and cornstarch are naturally gluten-free, but always check labels to avoid cross-contamination if you have a gluten sensitivity or celiac disease.
• Gluten-Free Tip: If you’re serving people with gluten intolerance, it’s best to use certified gluten-free tamari and double-check all ingredient labels.
