Using a Bamboo Steamer Basket is a gentler process than boiling, simmering, or poaching food, so it retains its shape, texture, color, and flavor. It’s healthier too, because no oil is required, and vital nutrients are locked in, rather than washed away. It is large enough to fit most foods and the right size to fit in most wok’s, pans, or pots. The stackable 2-tier design allows different food to be streamed simultaneously.
