Anniebach sorry, I've only just returned to this thread and seen your question. An Instant Pot, as someone else mentioned, is an electric pressure cooker, with several functions that traditional stove top pressure cookers don't have. It has built in programmes for cooking rice, meat/stew, poultry, soup, porridge. It even has a yoghurt programme - I make yoghurt regularly in it! It can also be used as a slow cooker, though I've never used this feature. Oh, and you can make cheesecakes in it, really amazing cheesecakes, cheesecakes to die for! probably why I'm always on a diet.
It really is a great addition to any kitchen - I wouldn't be without mine
have a look at it here
