Sesame oil is used in stir-fries and fried dishes as well as for seasoning. It has a delicious aroma and a rich, nutty flavour, and has the effect of reducing gbadh cholesterol. Extracting the oil from toasted seeds gives the oil a strong aroma and a dark brown colour. If fresh seeds are used, the oil tastes richer and its colour is lighter. A special oil is available for frying tempura, the lightly-battered fish and vegetable dish which is hugely popular in Japan.
