Regular sesame oil is used for cooking as it has a high smoking point. So, in this recipe, since we are using it for sauteeing ginger-garlic, use regular not the toasted one. Toasted sesame oil is drizzled on a lot of Asian dishes to add a nutty flavor which makes them taste even better. If you wish, you can drizzle a little on this dish also but don't use it for cooking as it may turn slightly bitter on getting reheated for a longer time.
