The following recipe and excerpt for Thai grilled chicken with sweet chili sauce are from “Barbecue: Smoked & Grilled Recipes From Across the Globe“ by Hugh Mangum . It’s available for purchase at Amazon.
This dish, gai yang, from northeastern Thailand, is the most popular grilled chicken dish in the country (and beloved street food in Bangkok). A whole chicken is marinated in garlic, lemongrass, cilantro (coriander) roots, soy sauce, and fish sauce, then chargrilled. It’s often served with sticky rice and the spicy dipping sauce, nam jim jaew.

- Combine the sugar and 1 tablespoon hot water in a large bowl and stir until the sugar is dissolved. Add the remaining ingredients, then set aside.
- Set aside the chicken for 1 to 2 hours to bring to room temperature.
- Preheat a grill to high for indirect grilling.
- Place the chicken, skin side up, on the cooler side of the grill and cook for 45 minutes, or until the internal temperature of the breast reaches 140 degrees F. Flip the chicken and place it on the hot side of the grill. Cook for another 3 minutes, until the skin is crispy. Set aside to rest for 5 to 10 minutes.
- Serve warm with sticky rice, the dipping sauce, and lime wedges.
