What is Sweet Chili Sauce?
Sweet Chili Sauce is a well-known condiment in South-East Asian Cuisine. It originated from Thailand and is called 'Nam Chim Kai' by the locals. It is simply made of peppers, vinegar, garlic, and sweeteners simmered in water until it turns into a thick sauce. Contrary to what many think, this dipping sauce is not overly spicy. Rather, it is comparable to a sweet and sour sauce but with a mild fieriness that makes it yummier and craveable!

Why make it?
We all know that sauces and condiments are readily available at various grocery stores or supermarkets. So why make it from scratch, right? Here are some of the best reasons:
- It is made of fresh ingredients and is infinitely cheaper compared to buying ready-made brands.
- Homemade condiments are free from preservatives or additives, making them safer and healthier to consume.
- Lastly, you can tweak the recipe according to your preferred taste. Do you want lesser sweetness? Use less sugar. Not spicy enough? Drop some chilis for added zing!
Ingredients Used
- Bird’s Eye Chili - you can use chili flakes or milder chilis if you prefer it less spicy.
- Red Bell Pepper - make sure to remove the seeds as they might add a bitter taste to the sauce.
- Onion - is used in this recipe as it gives a mild sweet taste.
- Garlic - it gives the sauce sharp and savory flavor.
- Potato Starch or Corn Starch is used to thicken the sauce.
- Vinegar for a little tanginess and acts also as natural preservative.
- Sugar for sweetness!
- Salt
- Water

How to make Sweet Chili Sauce?
- Remove the tops and seeds of bell pepper and chili.
- Pulse bell pepper, chili, onion, garlic, and water until finely chopped.
- Transfer to a saucepan and add sugar, salt, and vinegar then simmer.
- Add the slurry to thicken. Serve or store.

Foxy tips for you!
- To keep from making the sauce too spicy, slice the chilis open then scrape off the seeds before chopping.
- Pulse the ingredients in intervals until you have very small pieces that are still somewhat distinguishable. Do not blend them to a paste.
- No food processor or blender, no problem! You can just chop the ingredients manually with your sharp knife or use a mortar and pestle. Just make sure you wash your hands thoroughly after.
- You can use any vinegar available, but if you prefer a milder one, you can use cane or rice vinegar to make the sauce tangy without being excessively acidic.
- Maintain a gentle simmer and continuously stir the mixture as it is cooking to avoid burning the sauce.

Shelf-life and Storage
Once the Sweet Chili Sauce is done, you can transfer it into a lidded jar and store it in the fridge for up to four weeks. The sugar and vinegar content in the sauce helps it last longer, but make sure you are not contaminating it with other food particles or it will lead to spoilage. Make sure to use clean utensils when getting the sauce from the jar. It is also ideal to sterilize the jars by boiling them in water before putting the sauce into the container.

Terry McDonald says
How much chili flakes is equal to 1-2 Birds eye chili chopped? You state the chili flakes can be a subsitite but did not say if it is 1/4 teaspoon or 3 tablespoons full. Thank you
Bebs says
I would say, start with 1/2 teaspoon of chili flakes. But it really depends on one's preference and of course how spicy your chili flakes are.

Can your sweet chili sauce be water-bath canned . for long term storage
Bebs says
Hi Joyce, This recipe is actually for home use and I haven't really tried canning it for commercial purposes (or even just to test) but I know that the commercially sold ones are with a preservative called sodium benzoate.
