Can you use a plastic colander for steaming?

It is not advisable to use a plastic colander for steaming food unless it is specifically labelled as heat-resistant and suitable for steaming. Ordinary plastic colanders are typically made of materials like nylon or polyethene, which may melt or release harmful chemicals when exposed to high temperatures used during steaming.

For safe and reliable steaming, it is best to use metal colanders (such as stainless steel) or bamboo steamers designed specifically for this purpose.
