A dolsot is a heavy granite bowl used in Korean cooking. They can withstand temperatures as high as 615 degrees F and remain hot for quite some time. It is often used for making hot stews and the dish dolsot bibimpap, a classic dish of rice, vegetables, egg and meat. Dishes are served bubbling hot in a dolsot.
A dolsot requires seasoning before use as the oils absorbed by the stone impart flavor to the food. Gently preheat the bowl and brush it with sesame oil. Wash your bowl with hot water only and never use soap, which the stone can absorb.
