The best thing about making your own sauce is that you can make it to suit your own taste. Store-bought sweet chili sauces are too sweet for my son, and they are too spicy for my daughter. But I can adjust the sweetness and spiciness with my homemade sauce.
Remove the stems and seeds from the red chili peppers. If you don't like it spicy, discard the seeds, and soak the chili peppers in the vinegar. But if you don't mind it spicy, soak the chili peppers together with the seeds in the vinegar to rehydrate.
When the chili peppers have become soft, finely chop them and put them back in the vinegar. Add the garlic, sugar, and salt to adjust the basic taste of the sauce.
Transfer to a pot, and turn on the heat. Over high-medium heat, let the sauce boil until it reduces to 1/2-1/3 while agitating the pot.
Skim off the scum while the sauce is bubbling away. When it's nearly done, the bubbles will become bigger, so watch it carefully...
When the sauce slightly thickens, it's done. When it's cool, it will thicken more. If you are making a small quantity, you can make it in the microwave, but be careful not to let it boil over!
Tips: If you don't like a strong sour taste, you can replace half of the vinegar with water. Compared to store-bought sweet chili sauces, this sauce is a little less sour and sweet.
So, using this sauce as a base, adjust the amount of chili pepper and sugar to suit your own taste.

I make fresh spring rolls quite often in place of a salad, but store-bought sweet chili sauces are too sweet for my son, and too spicy for my daughter. So, even though they wanted to eat lots of fresh spring rolls, they couldn't!! That's why I started making my own sweet chili sauce at home. It's easy to make, so I make it every time I need it, but it can also be stored.
You can finely chop the garlic instead of grating it. It's even easier if you use the tubed type of grated garlic. The sauce will thicken too much if you overcook it. If it hardens, dilute it with a little water. Adjust the spiciness and sweetness to suit your taste!
