My sister-in-law passed this on to my husband, who loves this dish. I believe she got it from a friend of ours, who lived on Guam for a while. It can also be cooked in a crockpot very well after the initial cooking--just add the browned chicken and all the other ingredients to the crockpot and let cook for 6 hours or so on low. The vinegar aroma is rather potent at first, so be prepared to open your windows! The end result is very tasty and tender. DH likes it over rice, to soak up the sauce.
