Sand Pot (Sha Guo) Technique (砂锅)
Ancient Chinese technique — used across all regions
Unglazed clay pots used for slow cooking, braising, and serving soups directly on the table. The porous clay allows moisture exchange, creating a distinctive cooking environment different from sealed metal pots. Sand pot cooking is foundational to Cantonese casseroles, Dongbei stews, and Fujian Buddha Jumps Over the Wall.
