Cut chicken thighs into bite-sized pieces. Pat dry to remove excess moisture — this helps them brown better.
Heat 3 tbsp roasted sesame oil over medium heat. Add the ginger first; pan-fry for about a minute until lightly browned. Then add garlic and Thai chilies.
(Tip: don’t use high heat — sesame oil has a lower smoke point and can burn, making the dish taste bitter).
Add chicken pieces to the pan. Stir and cook until slightly browned on all sides.
Pour in 3 tbsp rice wine, light soy sauce, dark soy sauce, and rock sugar.
Bring to a boil, then lower the heat. Let it simmer for about 8–10 minutes, until the sauce thickens and becomes glossy.
Turn off the heat and add a handful of fresh Thai basil leaves for that aromatic finish. Enjoy hot over a bowl of steamed white rice.
