Bamboo steamers impart a subtle flavor and prevent condensation buildup, while metal steamers are more durable, easier to clean, and heat up faster. The choice depends on your preference for flavor, maintenance, and cooking speed.
Bamboo steamers are traditionally used in Asian cuisine. They are made from woven bamboo and typically consist of stackable tiers and a lid. The bamboo material absorbs excess moisture, preventing condensation from dripping onto the food, which can make it soggy. Bamboo also imparts a subtle, earthy flavor to the food being steamed. However, bamboo steamers require more maintenance. They need to be thoroughly cleaned and dried after each use to prevent mold growth. They also tend to heat up slower than metal steamers.
Metal steamers, usually made of stainless steel, are more modern and versatile. They heat up quickly and are very durable. Metal steamers are also much easier to clean, often being dishwasher-safe. However, metal does not absorb moisture, so condensation can be an issue. Some metal steamers have features to mitigate this, such as vented lids or tiered designs that allow condensation to run down the sides. Metal steamers also do not impart any flavor to the food.
When using a bamboo steamer, line the bottom with parchment paper or cabbage leaves to prevent food from sticking and to make cleanup easier.
