Do you use store bought or homemade chili sauce?
I googled recipes and experimented until it had the taste I like. The sauces heat may vary depending on what type of chilies you use.
150 g chilis, you can use sweet peppers to make the sauce milder
2 dl white wine vinegar
2 dl sugar
4 tbs fish sauce
3 tbs sherry
4 coves of pressed garlic
2-3 tps corn starch in a little cold water
Clean the chilis you want to use and put all the seed in a cooking pot, then finely chop the chilis and add them to the pot with the seeds.
Add the rest of the ingredients with the chilis and cook to a boil, then reduce the heat to medium and let the sauce simmer for about 10 minutes. Remember to be careful breathing close to this concoction, the chilis and vinegar are really a sinus cleanser.
While the sauce is simmering add the cornstarch and water mixture and let it cook until the sauce thickens.
Remove the sauce from the heat and taste. You are supposed to taste sweetness, then tartness, then heat and the salty notes.
Not sweet enough add sugar, not hot enough add chilis and so on. Pour the sauce in sterile jars for storage or use it right away.
I used my sauce with som fish nuggets.
