This is a traditional Korean stone bowl, known as a "Dolsot," specifically designed for preparing and serving Bibimbap, a popular Korean dish. The bowl is made from stone, which retains heat exceptionally well, allowing the food to continue cooking and sizzling when served. The 18cm size is ideal for individual servings. Even though it doesn't come with a lid, the bowl itself is perfect for creating the signature crispy rice at the bottom of the Bibimbap, enhancing the dish's overall flavor and texture.
