Perilla Oil

들기름Deulgireum

Perilla frutescens

荏油(Imyu) - Perilla Oil — 荏 (perilla/wild sesame) + 油 (oil)蘇子油(Sojayu) - Perilla Seed Oil — named after the perilla seed (소자/蘇子) from which it is pressed

Perilla oil is the secret soul of Korean temple cuisine. While toasted sesame oil gets international recognition, perilla oil — pressed from the seeds of the wild perilla plant (들깨, deulkkae, literally 'wild sesame') — is arguably more distinctly Korean. The perilla plant grows wild across Korean hillsides and has been cultivated since the Three Kingdoms period (before 668 CE). It was likely one of the earliest oilseed crops in Korean agriculture. What makes perilla oil extraordinary is its omega-3 content: it contains up to 60% alpha-linolenic acid, one of the highest concentrations of any plant oil on earth, exceeding even flaxseed oil in some analyses. Korean Buddhist monks, who avoid all animal products including fish, relied on perilla oil as their primary source of essential fatty acids for centuries — an intuitive nutritional wisdom that modern science now fully validates. The roasted variety of perilla oil has a haunting, complex flavor that is impossible to replicate with any other oil. When you smell it, you smell Korea's mountains and temples. It is deeply tied to Korea's identity as a cuisine shaped by Buddhist and agricultural traditions.

Seasonal Availability

🍂AutumnAvailable year-round

Perilla seeds are harvested in September-October in Korea. Freshly pressed autumn oil has the most vibrant, grassy-nutty flavor. The oil oxidizes relatively quickly, so buy in small quantities and use within a few months of opening. Store in a cool, dark place.

Complementary Ingredients (궁합 재료)

Eggplant

The definitive temple food pairing: warming perilla oil perfectly balances eggplant's cooling nature, creating harmony of thermal properties and a rich, satisfying dish

Source: Korean Buddhist temple cuisine tradition

Shiitake Mushroom

Perilla oil's herbaceous depth magnifies the mushroom's woodsy umami — together they form the flavor backbone of many temple dishes

Lotus Root

A drizzle of perilla oil over stir-fried or braised lotus root adds warmth and complexity to the root's clean sweetness

Processing Methods (법제)

Cold-pressing(냉압착)

Cold-pressing perilla seeds preserves the delicate omega-3 fatty acids and aromatic compounds that heat would destroy. Premium Korean perilla oil is always cold-pressed.

Roast-then-press(볶은 후 압착)

Lightly roasting the seeds before pressing produces a darker oil with a deeper, more toasted flavor — this is the most common style used in Korean cooking and temple food.

Consumption Tips by Health Goal

Brain health

Use as a finishing oil drizzled over cooked dishes rather than for high-heat frying. The omega-3 ALA is heat-sensitive. A tablespoon daily provides significant brain-nourishing benefits.

Skin health

Incorporate regularly into daily meals as a dressing oil. The omega-3 fatty acids and vitamin E work together to hydrate skin from within. Consistent daily use yields the best results.

Respiratory health

Mix a small amount of perilla oil into warm honey water for a soothing throat and lung tonic during dry seasons or when experiencing a dry cough.

Culinary Profile

Flavor

Distinctively herbaceous, grassy, and deeply nutty — quite different from sesame oil. Has an earthy, almost wild quality with subtle minty-herbal undertones that evoke the Korean countryside

Texture

Rich, slightly viscous oil with a smooth mouthfeel; lighter on the palate than sesame oil despite its full flavor

Common Uses

Temple food dressing — the defining oil of Korean Buddhist cuisineGaji-namul — the classic eggplant-perilla oil combinationNamul dressing — used instead of sesame oil for an earthier flavorBibim-guksu — finishing oil for cold spicy noodlesBuchimgae — used in savory pancake batters for fragrance

Western Substitutes

Toasted sesame oil (the most common substitute, different flavor but similar role)Walnut oil (similar omega-3 richness and nutty flavor)Flaxseed oil (similar omega-3 content, but use only unheated)Extra-virgin olive oil (different flavor profile, but similar health benefits)
