I’ve been eating perilla oil my whole life, but it wasn’t until I was formally introduced to it by my mother a decade ago that I realized it.
I was trying to make kimchi pancakes in my NYC apartment but couldn’t replicate the taste of my mother’s and grandmother’s. During a phone call one day, I asked for my mother for the recipe and voilà, the generation-kept secret was revealed: perilla oil. As it turns out, many of the Korean dishes that I grew up eating contained perilla oil without my knowledge. My mother drizzles it over bibimbap, sautéed spinach, braised burdock root, stir-fried fish cakes, and, my favorite, spicy braised tofu. My grandmother adds it to miyeok guk (seaweed soup), gosari namul (stir-fried bracken), kkaennip-jangajji (marinated perilla leaf), and plain steamed rice with a dash of seasoned soy. My grandfather uses it as a dipping sauce when we have samgyupsal or galbi.
Once the distinctive scent and taste I’d been searching for since leaving Korea was finally available to me, I set out to gather as much knowledge as I could, constantly probing my mother’s and grandparents’ brains on my visits back. I started by assisting in their kitchens and asking questions: How was it produced? Where did it come from? Why did they use it compared to other oils? If my mother didn’t have the answer, she would call my grandmother, who had obtained the knowledge from the generation that came before. And I continued to expand my knowledge by consulting them on my ideas to use perilla oil in less traditional ways.
While each oil in my collection (walnut, sesame, pumpkin seed, olive, chili, peanut, the list goes on) has a special place in my kitchen, perilla oil is a constant staple for its versatility, flavor, and complexity.
So what is perilla oil?
Perilla oil is the oil produced by cold-pressing seeds of the perilla plant. The leaves, also known as Japanese shiso, Chinese basil, and kkae-nip, can be eaten raw or cooked, and the byproduct (a.k.a. press cake) of oil-making is used as animal feed or fertilizer. (The whole plant is used, an example of “no waste” mentality.)
What’s the flavor profile?
The flavor of perilla oil can be described as nutty and earthy, with a licorice, anise finish. Texturally, it coats the tongue with a velvety smooth feeling, adding richness. The two types of perilla oil are toasted (a.k.a. roasted) and untoasted. The toasted oil, which is a shiny, light brown color, tastes bolder and more assertive than the untoasted, which has a vibrant golden hue. On top of adding flavor and texture, perilla oil also contains high levels of omega-3 fatty acid, as well as omega-6 and omega-9 fatty acids. These are known to confer anti-inflammatory and cardiovascular benefits and to support healthy immune function.
How do you use it?
When I’m deciding whether to use toasted and untoasted perilla oil, I leave it to personal taste. Having grown up with toasted perilla oil, it’s what I gravitate towards for cooking, marinating, and finishing. When using it to cook, treat it like butter or unrefined coconut oil, being careful not to use high heat, which will impart a bitter taste.
Use it to lightly sauté any ingredient that will compliment its nutty, earthy flavor, such as mushrooms or spinach. Try putting it into a pesto of summer greens such as watercress, arugula, and dandelion greens. Or make a fresh dip with yogurt, perilla leaf, oil, and lemon juice to enjoy with crudité. When making vinaigrettes and soups (it would be great in a refreshing summer strawberry gazpacho), add perilla oil to the emulsifying process of the recipe.
