Perilla leaves, often overlooked but profoundly versatile, are a hidden gem in both the culinary world and traditional medicine. Also known as shiso in Japanese cuisine, and kkaennip in Korean, these aromatic leaves boast a unique flavor profile and a wealth of health benefits. This article delves into the myriad ways you can incorporate perilla leaves into your life, from tantalizing dishes to natural remedies.
A Flavorful Journey: Culinary Uses of Perilla Leaves
Perilla leaves offer a distinctive flavor, often described as a blend of mint, basil, anise, and even a hint of cinnamon. This complexity makes them a wonderful addition to a variety of dishes, lending a refreshing and aromatic touch. The flavor can vary slightly between the green and red varieties, with the red often having a more intense, almost spicy, note.
Perilla Leaves in Asian Cuisine
Perilla leaves are a staple in East Asian cuisine, particularly in Korean and Japanese dishes. They are frequently used as a wrap for grilled meats, adding a burst of flavor and freshness.
In Korean cuisine, kkaennip is a key ingredient in kimchi. Its distinct aroma contributes significantly to the fermentation process and the overall taste of the final product. You’ll also find it used in salads, pancakes, and stir-fries. A popular dish is kkaennip jeon, a savory pancake made with perilla leaves, flour, and other vegetables.
Japanese cuisine embraces shiso in various forms. It’s a common garnish for sashimi and sushi, adding a visual appeal and a refreshing counterpoint to the richness of the fish. Tempura shiso leaves are a delicious and crispy treat. You might also encounter it finely chopped in salads, mixed into rice dishes, or used to flavor pickled plums (umeboshi).
Beyond Asia: Expanding Perilla’s Culinary Horizons
While predominantly used in Asian cooking, perilla leaves can enhance dishes from other cultures as well. Their unique flavor profile complements Mediterranean flavors beautifully.
Consider adding chopped perilla leaves to salads with feta cheese, olives, and a lemon vinaigrette. They can also be incorporated into pesto, providing a unique twist on the classic basil-based sauce. Try adding them to pasta dishes or using them as a topping for grilled vegetables.
Creative Culinary Applications
The possibilities for incorporating perilla leaves are truly endless. Let your creativity guide you as you explore these less conventional uses.
Infuse oils with perilla leaves to create a flavorful dressing or marinade. Dry perilla leaves and grind them into a powder to use as a seasoning for meats, vegetables, or even popcorn. Add perilla leaves to cocktails and mocktails for a refreshing herbal note. Think of a perilla mojito or a perilla-infused lemonade.
Consider using them in desserts. Perilla leaves can be infused into creams, custards, and ice creams for a unique and subtle flavor. Candied perilla leaves are a beautiful and delicious garnish for cakes and pastries.
The Healing Power of Perilla: Medicinal Properties

What are perilla leaves and where do they originate?
Perilla leaves, also known as shiso in Japanese cuisine, are aromatic leaves belonging to the mint family, Lamiaceae. They are native to Southeast Asia, specifically regions of China, Korea, and Japan, and have been cultivated there for centuries. These leaves are highly valued for their distinctive flavor profiles, which vary depending on the variety, ranging from licorice-like and anise-like to minty and citrusy.
Perilla plants are annual herbs that typically grow to a height of one to two feet. They possess broad, serrated leaves that come in different colors, including green, purple, and a combination of both. Due to their adaptability and ease of cultivation, perilla plants have spread to other parts of the world and are now grown in various countries with suitable climates, including some areas of North America.
What are the different varieties of perilla and how do their flavors differ?
There are primarily two main varieties of perilla: green perilla (Perilla frutescens var. crispa) and red (or purple) perilla (Perilla frutescens var. purpurea). Green perilla is known for its milder, slightly minty, and somewhat anise-like flavor. It’s often used as a garnish, in salads, or wrapped around sushi and sashimi to add a refreshing herbal note.
Red perilla, on the other hand, has a more pronounced and bolder flavor. It carries a hint of cinnamon or clove alongside its anise-like undertones. Its stronger taste makes it suitable for pickling, coloring foods (especially umeboshi plums), and flavoring cooked dishes. A third, less common variety is known as bicolor perilla, which features green leaves with purple undersides and possesses a flavor profile that blends characteristics of both the green and red varieties.
What are the primary culinary uses of perilla leaves?
Perilla leaves are incredibly versatile in the culinary world, offering a unique flavor enhancement to numerous dishes. In Asian cuisines, particularly Korean and Japanese, they are used extensively as a fresh herb, adding a bright and slightly spicy note to salads, wraps, and marinades. They are frequently served alongside grilled meats, raw fish, and in noodle dishes.
Beyond their fresh usage, perilla leaves are also utilized in cooked preparations. They can be stir-fried with vegetables or meats, added to soups and stews for flavor depth, and even deep-fried for a crispy snack. Furthermore, perilla seeds are pressed for their oil, which is used in cooking and seasonings, while the leaves themselves can be pickled or used to flavor sauces and condiments.
What are the potential health benefits associated with consuming perilla leaves?
Perilla leaves are packed with beneficial compounds that contribute to their potential health benefits. They are a rich source of antioxidants, which help protect the body against cellular damage caused by free radicals. Additionally, they contain anti-inflammatory compounds that may help reduce inflammation throughout the body and alleviate symptoms of conditions like arthritis.
Studies suggest that perilla leaves may also possess anti-allergenic properties, potentially helping to alleviate symptoms of allergies like hay fever and asthma. Furthermore, they contain compounds that may have antimicrobial and antiviral effects, contributing to a stronger immune system. It is important to note that further research is needed to fully confirm these benefits.
Are there any potential side effects or precautions to consider when consuming perilla leaves?
While generally considered safe for consumption, some individuals may experience mild side effects from eating perilla leaves. In rare cases, allergic reactions can occur, manifesting as skin rashes, itching, or digestive upset. People with known allergies to other members of the mint family, such as basil or oregano, should exercise caution when trying perilla.
Perilla leaves contain oxalates, which can bind to calcium and potentially contribute to kidney stone formation in susceptible individuals. Therefore, those with a history of kidney stones or kidney problems should consume perilla in moderation. Additionally, pregnant and breastfeeding women should consult with their healthcare provider before consuming large quantities of perilla leaves, as there is limited research on its effects during these periods.
How should perilla leaves be stored to maintain their freshness and flavor?
To keep perilla leaves fresh and flavorful for as long as possible, proper storage is essential. After purchasing or harvesting, gently rinse the leaves under cool water and pat them dry with a paper towel. This helps remove any dirt or debris and prevents excess moisture from accelerating spoilage.
Wrap the dried perilla leaves loosely in a slightly damp paper towel and place them in a perforated plastic bag or a container with a lid. Store the bag or container in the refrigerator’s crisper drawer, where the humidity is optimal. This method helps maintain moisture levels and prevents the leaves from drying out or wilting. Properly stored perilla leaves can typically last for up to a week in the refrigerator.
Can perilla leaves be grown at home, and what are the basic requirements for cultivating them?
Yes, perilla leaves can be successfully grown at home with relatively little effort. They thrive in warm climates and require well-drained soil that is rich in organic matter. Choose a sunny location that receives at least six hours of sunlight per day. You can start perilla from seeds indoors several weeks before the last expected frost or directly sow them into the garden after the danger of frost has passed.
Water regularly to keep the soil consistently moist, but avoid overwatering, which can lead to root rot. Fertilize the plants every few weeks with a balanced fertilizer to promote healthy growth. Pinch off the top growth to encourage bushier plants and more abundant leaf production. Regular harvesting of the leaves will also stimulate continued growth throughout the growing season.
