Hi, yes I agree, the Supermarket Chili Sauces (any brand) sucks. Here my favorite recipe, very nice....
Chili-Sauce:
5 big, red Chilies (deseeded)
3 small red Chilies (Padi)
8 cm young ginger
2-3 T Calamansi or Lime Juice
8 garlic pods
skin from small Calamansi, finely sliced
1 ½ T Sugar
¾ bis 1 t Salt
½ cup Chicken Stock
Use a mortar to pound the Chilies, add garlic and salt, then the ginger. Put Salt and sugar and add enough chicken stock to taste. At the end, put some Calamansi Juice and the finely sliced skin of a Calamansi.
Enjoy!
