This oil is used for a dish called sesame oil chicken, it should be more expensive than regular sesame oil. It is a Taiwanese dish. Or there are variations of it like sesame oil liver or sesame oil kidney. It tastes best made with no water and all rice wine. People like to traditionally accompany this with somen-ish noodles (mien shien) but I don't like it as much because you have to eat it really fast or the noodles grow in size.
