My all time favourite CCF is located in Penang's Genting coffee shop and according to vkeong's blog, they put peanut butter into the sauce. So that might explain the 'sweety caramel' taste and the 'brown to black' coloured sauce.

I have personally tried this recipe twice. As I planned to bring this dish to a pot luck, I was a little bit worried that not many people like having coriander. But in the end, every one came to me and told me that the taste was great. Even people who do not normally take coriander thought the taste was acceptable. It only took me 15-30 minutes to grill the chicken. Very easy recipe and very tasty.
