You are going to love your Instant Pot. I use mine daily to make hot cereal every morning to soups, cakes, bean dishes etc. this website you will find addictive like many of us do!
Instant pot unfortunately doesn’t come with a steamer basket. You can find steamer baskets to fit it online such as Amazon. I use a stainless steel one from an older Presto pressure cooker I have. I would also suggest looking in second hand stores for a steamer basket. I have found wonderful accessories for my kitchen at our local Value Village and Salvation Army thrift stores. Try them too.
Recently, I purchased a double decker collapable steamer from Kuhn Rikon. It was pricy at $30 Cdn but I am finding it indispensable.
Enjoy your pressure cooker and welcome to the club.
Warmest regards,
