When winter arrives in Korea, warm bowls of soup and hearty stews become daily comfort. Among these beloved ingredients, siraegi — dried radish greens — holds a special place in Korean winter cuisine. Once considered a humble food, siraegi is now celebrated as a nutritious, flavorful, and culturally rich ingredient.
In this article, you’ll discover what siraegi is, how it became part of Korean food culture, its nutritional benefits, and the best dishes to enjoy during the colder months. Let’s explore why Koreans cherish this simple yet powerful winter ingredient.
What Is Siraegi?
Siraegi is made by drying the leafy tops of Korean radishes, called mucheong. In the past, families dried leftover radish leaves after harvesting so they could enjoy vegetables throughout the long winter. This simple preservation method eventually became a cherished culinary tradition.
Historically, Koreans used every part of the radish. The leaves were braided and hung in shaded areas to dry. Once rehydrated, they were cooked into soups, stews, or seasoned side dishes. During the Joseon era, siraegi was considered one of the essential “winter survival foods” thanks to its long shelf life and nutrition.
Today, people grow radish specifically for producing high-quality siraegi. What began as a resourceful habit has now transformed into a beloved winter delicacy enjoyed for its deep flavor and impressive health benefits.
The Nutritional Benefits of Siraegi
Siraegi may look simple, but it is packed with vitamins, minerals, and dietary fiber. Here are the key health benefits:
✔ Supports Digestion & Gut Health
Siraegi is rich in dietary fiber, which helps digestion, supports a healthy gut, and prevents constipation.
✔ Strengthens Immunity
Loaded with vitamins A and C, siraegi helps boost immune function — especially important during cold winter months.
✔ Promotes Bone Health
Its high calcium content supports strong bones and teeth, making it beneficial for children, adults, and seniors.
✔ Reduces Excess Moisture in the Body
Traditional Korean medicine views siraegi as an ingredient that removes internal dampness, helping reduce swelling and promoting balance.
✔ Warms the Body
Siraegi has a naturally warming quality that promotes blood circulation — perfect for freezing winter days.
