Electric pressure cooker, has a pretty big following - have a search around the web. Cheaper than what I paid for the 6L!
It's great in that there's far less smell etc than even a stove-top pressure cooker, it can do anything from slow cooking, stews, rice to porridge and yogurt. Would suggest getting a replacement silicone ring (use one for smelly foods and one for others) and a lid of some sort if you decide to get one.
