any1 knows how to make the thick Chee Cheong Fan sauce?

I just know how to make those thinner one like chinese ppl eat in Dim Sum,
Just add 4 table spoon of sugar, 2 table spoon sesame oil, 4 tablespoon of water and 4 table spoon of soy sauce and then stir well, there you have the sauce.

The sauce also can be use in chicken rice as the sauce

most likely, but it's for the Chee Cheong Fun, it has a sweety caramel and s mild salty from brown to black flavour.. i'm not sure, but i'll try the corn flour as u recommend 1st see how it goes.
