Heat the oil. Heat the oil in a large wok or pot over medium heat until it shimmers.
Fry the curry paste. Add the green curry paste and fry, stirring, until it loosens up and smells fragrant.
Build the curry sauce. Pour in the coconut milk and stir to combine. Add the palm sugar, fish sauce, salt, and rosdee seasoning powder. Bring to a gentle simmer and make sure the palm sugar dissolves.
Cook the pork. Add the pork and stir gently until the meat turns opaque and feels tender, about 3 minutes.
Add the vegetables. Add the Thai eggplants, yard long beans, pea eggplants, and chilies if using. Let the curry simmer until the vegetables are tender but still hold their shape.
Finish with basil and serve. Turn off the heat, add the sweet basil, and give everything a gentle stir. Serve hot with jasmine rice or rice vermicelli noodles.
