The Thai name is "Pat Pak Bung Fy Daeng". From David Thompson's book, Classic Thai Cuisine. David says, "This stir-fry is a favourite of the Thais. Often they crumble a little roasted kapi (shrimp paste) and a few dried prawns (shrimp) into this dish." He also says that any green vegetable can be used in place of the Siamese watercress, such as spinach or asparagus.
