Introduction to Perilla Leaves

Perilla leaves, or Perilla herb, also known as Perilla frutescens, is highly valued in Asia but often viewed as an intrusive weed in the West. This plant has been grown since ancient times and remains a popular crop in East Asia. 

Perilla leaves, often translated from Korean to English as sesame leaves (깨 = sesame, 잎 = leaves), are a fundamental ingredient in Korean cuisine, revered for their unique flavor and aroma. 

These vibrant green, heart-shaped leaves come from the Perilla frutescens plant, which belongs to the mint family. They are commonly used for their culinary and medicinal properties, making them an essential element in Korean cooking.

History and Cultivation

Perilla leaves have a rich history in East Asian cultures, dating back over two thousand years.

They are native to the mountainous regions of China, India, Japan, and Korea. In Korea, perilla leaves have been cultivated for centuries for both culinary and medicinal purposes.

The plant is known for its resilience, thriving in various climates and soil types, making it a staple in Korean agriculture.

Culinary Uses in Korean Cuisine

In Korean cuisine, perilla leaves are celebrated for their versatility. They are often used as a wrapper for grilled meats, such as bulgogi, or as a key ingredient in ssam, a traditional dish where meat or other fillings are wrapped in leaves.

Additionally, perilla leaves are used to make kimchi, a famous Korean fermented side dish. These leaves add a distinct earthy and minty flavor to dishes, enhancing the overall taste and aroma.

Nutrition and Health Benefits of Perilla Leaves

The uniquely aromatic perilla leaves, a staple in Korean cuisine, are not only cherished for their distinctive flavor but also for their impressive nutritional profile.

Packed with vitamins and minerals, perilla leaves are a rich source of Vitamin A, C, and riboflavin, which boost the immune system and promote healthy skin.

They also contain a bounty of antioxidants, which play a critical role in neutralizing harmful free radicals in the body. Importantly, these leaves are laden with alpha-linolenic acid, an omega-3 fatty acid that is crucial for heart health and may help reduce inflammation.

For those watching their caloric intake, perilla leaves offer a myriad of health benefits without the surplus calories, making them an excellent addition to a balanced diet.

How to Select and Store Perilla Leaves

When choosing perilla leaves, look for vibrant green foliage that is crisp and free from spots or wilting; this indicates freshness and quality.

 After purchasing, the leaves demand careful storage to maintain their integrity. It's advisable to wrap them loosely in a paper towel to absorb excess moisture and store them inside a plastic bag in the refrigerator's crisper drawer. This method helps preserve their characteristic peppery bite and aromatic essence.

With proper storage, perilla leaves can maintain their freshness for about a week, allowing you to savor their flavor in numerous dishes.

Popular Korean Recipes Using Perilla Leaves

Korean cuisine celebrates perilla leaves in a variety of flavorful dishes that showcase their versatility. One popular creation is 'kkaennip kimchi' (깻잎 김치), a spicy and savory pickled delicacy that brings out the rich taste profile of the leaves.

Another beloved recipe is 'kkaennip jeon' (깻잎전), a type of Korean pancake dish where the leaves are coated in a batter and pan-fried to golden perfection, often served as a delectable appetizer or side dish.

Soy pickled Kkaennip, Kkaennip Jangajji (깻잎 장아찌), is another favorite.

For those who enjoy wraps, 'ssam' is a must-try—a dish where perilla leaves can be used to wrap morsels of grilled meat, rice, and a dollop of spicy sauce, creating a symphony of flavors that is both nutritious and satisfying. 

Substitutes for Perilla Leaves in Cooking

Perilla leaves have a unique flavor profile, making them challenging to substitute directly.

However, if perilla leaves are unavailable, you can use a combination of shiso leaves, mint, and basil to mimic the herbaceous and slightly minty taste of perilla leaves.

Alternatively, you can use a mix of sesame leaves and a small amount of sesame oil to achieve a similar nutty and aromatic essence in your dishes. 

When using substitutes, keep in mind that the flavor may not be an exact match, but it will still contribute to a delicious final dish. Experiment with different combinations to find the best alternative for your specific recipe.

Where to Buy Perilla Leaves

Perilla leaves can be found in Korean or Asian grocery stores, either fresh or dried, depending on the season and location.

Additionally, some specialty food markets or online stores that specialize in Korean ingredients may also carry perilla leaves.

When purchasing perilla leaves, look for fresh, vibrant green leaves with no wilt or discoloration for the best flavor.

Growing Perilla

A warm climate, well-draining soil, and full sun are ideal for Perilla. You can grow Perilla from cuttings or seeds. If you decide to plant Perilla from seeds, sow them directly into the soil after the last frost date.  Plant seeds or seedlings about 12-18 inches apart so that they will have enough room to grow. Until the seeds germinate, keep the soil moist.

To promote healthy growth, fertilize perilla plants every 4-6 weeks with a balanced fertilizer during the growing season. Perilla plants prefer moist soil, so water regularly, especially during dry periods.

In order to prevent the plant from going to seed too soon and to encourage leaf growth, pinch off the flowers as soon as they appear .

Harvest the leaves once the plant has grown a few true leaves. Simply snip off the outer leaves or harvest the whole plant, leaving a few leaves behind.

Keep an eye out for pests such as aphids and caterpillars and treat them as soon as they appear. Good airflow around the plants can help prevent diseases such as powdery mildew.
