Lime Chicken in coke

I was told by my lao gong that this is a popular dish in China and Taiwan,the reviews I seen on a food forum make me curious to attempt it for myself.I modify some of the ingredients,but the amount of coke used remains the same.Oddly enough,though the chicken was basically cooked in cola-cola,we cannot detect the slightest hint of the coke at all.Instead,it mellow into a sweet,thick gravy that tasted like braised moist,succelent chicken that goes well with rice/noodles.Can try it if you,too,are curious...hehe...

5 pieces of chicken thighs
