Cooking researcher and nutritionist Aya Osada uncovers the benefits of wild sesame oil in this final instalment of our four-part series on essential Japanese ingredients.
A
little bit of egoma (wild sesame) oil goes a long way in Japanese cuisine. You might be familiar with shiso, the little plant whose leaves are widely used in Japanese dishes. But have you heard of egoma? It’s easy to confuse the two. Also known as wild sesame in English, egoma looks like the bright green shiso yet its leaves are rounder and firmer than shiso. They also taste different. Egoma originates from Southeast Asia and also grows in the mountain ranges of India and China, in Yunnan province. Historically, egoma made its way from these places to Japan and Korea. In Japan, egoma is considered to be the oldest oil as traces of what had already been cultivated have been found at several ancient sites that date from between 5,500 and 10,000 years ago. Egoma was used to fuel lamps in the early Heian period (794 to 1185) and as an industrial oil for painting umbrellas, lanterns and crafts in the mid-Edo period (1603 and 1868). Egoma has been used as food in Japan for only a short period. But the health boom in the country in recent years has led many to give egoma a second look. After all, the plant is used widely in neighbouring South Korea, where there is a traditional

food culture of eating egoma leaves and making kimchi with egoma. In Japan, egoma seeds are ground and used in a sauce for a traditional snack known as gohei mochi, grilled rice cake with a sweet walnut miso paste. ALL ABOUT EGOMA OIL Oils and fat are an essential part of a healthy diet. Instead of saying “oil makes us fat” or “animal fat increases cholesterol levels”, we should be paying attention to the benefits of fatty acids in oil and consider using healthy oils in a well-balanced diet. Omega-3 fatty acids (α-linolenic acid) and omega-6 fatty acids (linoleic acid) are essential fatty acids that cannot be made in our bodies. It is important to take these two fatty acids in a well-balanced manner. Modern diets tend to include too much omega-6 and too few omega-3 fatty acids. Recent reports have noted that the imbalance between omega-6 and omega-3 fatty acids is one of the causes of allergies and lifestyle-related diseases. Because omega-3 fatty acids cannot be made by the human body on its own, they need to be included in your daily diet. Egoma oil is high in omega-3 fatty acids and is a good ingredient to add to a healthy diet.
