I have one which has a metal body which sits on a hotplate (Morphy Richards), which I can use for browning before hand on the stove. And I have one with a crock (not the teeny one), which I can't. I also have one which fits inside a Tefal steamer, which does seem to give a fresher taste, but which has one snag. The pot, plastic, has split. It needs a liner. Where do I get them from? What are they like?
