Ha Sun is a traditional Korean dish made from fermented vegetables, primarily napa cabbage and radishes. It is seasoned with a variety of spices, including red pepper flakes, garlic, and ginger, which give it a distinctive flavor. This dish is a staple in Korean cuisine and is often served as a side dish, known as banchan. The fermentation process not only enhances the taste but also provides health benefits, such as probiotics that aid digestion. Ha Sun is commonly enjoyed with rice and other main dishes, making it a versatile addition to meals in Korean households.
