Chicken thighs are simmered in water with ginger, chilies, lime zest and fish sauce until cooked through. Lime juice and honey are poured in and the chicken continues to cook until the liquid caramelizes and coats the chicken.
Cook over high heat, uncovered, turning the chicken thighs often until the sauce browns and thickens. Watch the chicken carefully at this stage — the fast-thickening sauce burns fast because of the honey.
When the liquid has evaporated and all there is left is a thick caramelized sticky sauce coating the chicken, lift the chicken pieces one by one and transfer to a serving platter.
