Looking for a rice cooker, steamer, deep fryer, slow cooker combo that can cook rice and steam at the same time
I want a car that can fly. :P

I say you have two options:


A quality dutch oven
. This can do it all, although steaming might be difficult unless you can find a steamer insert for your dutch oven. It's certainly the closest you're gonna get to a slow cooker.
A quality stock pot with a steamer insert (or two). I have a great 12 qt stock pot
with 2 steamer inserts. I deep fry in it often, the high sides contain spatter. The only thing it doesn't do well is slow cook.
