Quinbo casserole roasted potatoes

I love to cook with casseroles, especially porridge. Recently, a Kunbo food-grade casserole, a previously unheard of "dry and cold" casserole, with good heating and time-delayed fever, is called the "breathing pot". The roasted potatoes in childhood memory are baked in a wide field with a earth kiln, but it's hard to eat the roasted potatoes anymore. Roast potatoes are on the streets of the city in the winter, and I can't afford to buy them because of the buckets. Today I'm making that long-defeated taste of my heart with a pot called "dry and cold"。
