The process is different. Traditional sesame oil is fried with sesame seeds. Big sesame seeds are ripe, and small sesame seeds are easy to paste when fried, so they have a paste smell when ground. Le Chun's sesame oil uses Japanese pressing technology, so it doesn't taste like you said, but the oil yield is higher when pressed. Lady Le Chun's sesame oil has few impurities, no peculiar smell and lasting fragrance. It tastes the same from beginning to end, and the bottle cap is also a unique seal.
