Yeah, I mentioned that before...it's tough here trying to find the right ingredients (I still haven't found any pak chi roots at any of the Thai stores).
And, unfortunately, the smallest chickens here are about 3-4 pounds...if I can even find them. Most of the time they are in the 5-6 pound range.
Usually for myself I cook smaller 1 pound chickens we call 'cornish game hens.' But it's not enough for things like this. And I would have used Thai chilis but the serranos are more spicy at this time of year (even my Thai chili plant has failed to make any spicy peppers yet).
