Dim sum bamboo steamer

Bamboo steamers for dim sum, essential in Cantonese cuisine, steam dumplings preserving texture and flavor.

About this subject

The bamboo steamer for dim sum, called long zheng (笼蒸), is a traditional utensil in Cantonese cuisine, used for centuries to steam food. Unlike metal pots, bamboo absorbs excess moisture, preventing dumplings from becoming soggy and preserving their delicate texture. Each steamer is handcrafted from thin bamboo strips, woven without glue or nails, and designed to stack in layers, allowing multiple types of dim sum to be cooked simultaneously, such as har gow (shrimp), siu mai (pork), and char siu bao (buns). The conical bamboo lid promotes even steam circulation, while the slatted base lets heat pass through. Culturally, dim sum is a morning or lunch meal served in tea houses (cha chaan teng), accompanied by Chinese tea. The use of bamboo steamers dates back to the Song dynasty (960, 1279), when steaming techniques were refined in the Guangdong region. To maintain the steamer, hand wash with warm water and air dry, avoiding strong detergents. Over time, the bamboo develops a distinctive aroma that enhances food flavor.
