Dim sum bamboo steamer

Bamboo steamers are essential for cooking dim sum, a Cantonese tradition that has spread worldwide.

About this subject

Bamboo steamers for dim sum, known as "zhēng lóng" in Chinese, are ancient cooking tools dating back to the Han Dynasty (206 BC, 220 AD). Traditionally handmade, they are crafted from dried bamboo strips tied together without glue or nails. Their circular, stackable design allows multiple layers to cook different items simultaneously as steam rises through the gaps. Each steamer typically measures 20 to 30 cm in diameter, and professional kitchens may stack up to ten tiers. Bamboo is chosen for its lightness, ability to absorb excess moisture, and subtle aroma that infuses the food. During dim sum preparation, the baskets are lined with parchment paper or lotus leaves (depending on the dish) and placed over a wok or pot of boiling water. Steaming times range from 5 to 15 minutes, preserving the texture and flavors of the ingredients. Dim sum, meaning "touch the heart" in Cantonese, is a meal of small portions served in bamboo steamers, traditionally enjoyed in tea houses (cha chaan teng) in Guangdong province and Hong Kong. This practice has spread globally, becoming an icon of Chinese cuisine. Notably, bamboo is one of the most sustainable materials for kitchenware, as it grows quickly and requires minimal replanting. Beyond its culinary function, many restaurants use the steamers for aesthetic presentation, stacking them on the table to create a visual experience.
