Assuming you always have to use a steamer basket
There are so many different ways to steam that it's commonly misunderstood that you need a special basket to get the job done. Even a pot, which is very useful and is usually the default vessel for steaming, is not the only option. Steaming, for example, can be done just as easily in carefully curated parchment pouches enclosed with food and liquid over an oven or stove as it can in an electric steamer.
You can even make your own steamer out of tin foil and a heat-resistant plate. According to Food Network, there are also effective steaming methods that use a disposable aluminum pie plate, an elevated cooling rack, and even the microwave. In an Instant Pot, you can also steam. Choosing a non-traditional steaming method may be determined by what you're cooking and how much effort you're willing to put in. A steamer basket is still relatively inexpensive and easy to find, so it may be worthwhile to invest in one, but don't be misled into believing that it is required for this cooking method.
