How to Make How to Make Sweet Chilli Sauce at Home
Step 1: Prep Your Chillies
Decide just how spicy you want your sauce to be: for a gentler heat, remove those fiery seeds from the red chillies. If you’re a fan of more intense spice, keep them in! Finely chop the chillies by hand for a rustic texture, or pulse them in a blender if you prefer your sauce silky-smooth. Either way, this is where all the lip-tingling vibrancy starts.
Step 2: Combine Main Ingredients
Grab a small saucepan and add your chopped chillies, vinegar, water, white sugar, fish sauce, and minced garlic. This bold group of flavors is where the magic of How to Make Sweet Chilli Sauce at Home truly comes alive – the moment when sweet, sour, salty, and spicy all mingle together.
Step 3: Bring to a Boil
Place your saucepan on the stove and bring the mixture up to a boil, stirring now and then to make sure the sugar dissolves completely. The scent alone will get your appetite going, as the tangy vinegar and aromatic garlic fill your kitchen.
Step 4: Thicken Your Sauce
Now it’s time for the cornstarch slurry. In a tiny bowl, mix the cornstarch with 2 tablespoons of water until smooth. Slowly stir this into the boiling sauce and let everything simmer for just 1 to 2 minutes. Watch as the sauce transforms: it’ll go from thin and runny to perfectly syrupy, ready to cling to anything you can dip.
Step 5: Cool and Store
Take your saucepan off the heat and let the sauce cool down completely. Pour it into a clean jar or bottle. The sauce will thicken a bit more as it cools, turning even glossier – and yes, it’s almost impossible not to dip something in immediately! Store it in your fridge, where it’ll keep for a full month (if you can resist finishing it before then!).
How to Serve How to Make Sweet Chilli Sauce at Home

Garnishes

Side Dishes

It’s also brilliant alongside fried chicken, grilled shrimp, vegetable tempura, or even fried tofu. This versatile condiment brings a sweet-spicy twist that brightens up so many side dishes and snacks.
Creative Ways to Present
Don’t just leave the sauce in a jar; pour it into ramekins or tiny dipping bowls for each guest, swirl it onto a platter under grilled skewers, or drizzle lines of sauce on top of roasted veggies for a gourmet finish. You can even brush it on burgers or use it to top grain bowls for extra flavor and stunning color.
Make Ahead and Storage
Storing Leftovers
Your fresh batch of sweet chilli sauce will happily hang out in a sealed jar in your fridge for up to a month. Be sure to use a clean spoon each time you dip in to keep it fresh and flavorful. It may thicken ever-so-slightly as it sits, but a quick stir will bring it back to dipping perfection.
Freezing
If you want to make a double batch and stash some for the future, you’re in luck: this sauce freezes beautifully! Just let it cool completely, pour it into a freezer-safe container (leaving a little space for it to expand), and freeze for up to three months. Defrost overnight in the fridge when ready to use.
Reheating
Once your sauce is chilled or thawed, you might notice it’s a bit thicker than you’d like. No problem! Simply reheat it gently on the stove or in the microwave with a quick splash of water to loosen it up, stirring until it’s glossy and smooth once again.
