When gai yang is good, it is something to write in a blog about. I never realized how good gai yang could be until I encountered a gai yang wichianburi ไก่ย่างวิเชียรบุรี seller down the underpass from where we were staying in South Central Bangkok. This guy's chicken was amazing. I ended up getting one chicken a week for lunch. His chicken was so good it was usually sold out by noon every day, so I would have to hit him up by 10am if I was to be lucky. When I picked up friends from the airport it was inevitably the first thing they put into their mouths.

There are a few different versions of gai yang. The one sold above is call gai yang wichianburi, which I gather originated in Wichianburi district in Petchabun province in Northern Thailand. The chicken is butterflied, marinated, bound into some bamboo splints and slow cooked over charcoal turning often to create a lacquered effect. The skin and outside meat is rendered and crispy, the meat is soft and well seasoned. Smaller 12-16oz chickens are used, promoting the tenderness of the meat. The size also helps in cooking and portioning, where your typical 2 1/2 -3 pound bird is unyielding and a bit much for 1 person to eat.
Other versions I have encountered are cooked on makeshift street side or highway side rotiserries and some are cooked in giant ceramic pots creating a tandoori-like chicken. All are eaten with sticky rice and are usually accompanied by a sauce.
The wichianburi chicken described above comes with a deeply spiced and slightly sweet tamarind based sauce. The sauce has a certain viscosity that sticks to the chicken when it is dredged through the sauce.
The marinade itself is also important. In addition to the holy trinity of Thai marinades, that is coriander root, black peppercorns and garlic, I like to add palm sugar, Thai soy sauce and a touch of some kind of booze like beer or whiskey. The marinade should also have a slight sticky viscosity that will stick to the chicken while it is grilling. The marinade should also help promote caramelization while it is slowly cooking over the charcoal.
Charcoal must be used to achieve gai yang greatness. No gas grill, no briquettes, no oven, but real charcoal. The slow smokiness achieved from charcoal will make your gai yang legendary.
The chicken must be smaller, never frozen and free range. Cornish game hens will work if need be, but try to find fresh birds.
If possible eat your gai yang with your hands, with sticky rice and with copious amounts of beer or whiskey.
Like most great things, gai yang is simple to eat, but cooking gai yang has the potential for disaster. However, if you can follow the rules in your tax return, you can make gai yang.
