I have a small pressure cooker which also slow cooks (vented). I LOVE it. What a time saver. Yesterday I used the pressured steam cook facility to cook double the potatoes I needed. I mashed them and saved half. This morning, after walking the dogs but before work I put beef, tinned toms, carrots, celery and a stock pot in on slow cook. Tonight, I reheated the mash and enjoyed a very tasty dinner with little washing up : )
The leftovers I will blitz with stick blender and that will be soup for tomorrows lunch.
It makes a great rice pudding on slow cook and it is also a savoury rice cooker but I have yet to try that.
I have got a conventional oval slow cooker but that is now in the cupboard as I mostly cook for tow.
