My daughter got me an All-Clad slow cooker for Mother's Day with a cast aluminum insert. I don't use aluminum for cooking because I'm not comfortable with it, and I've been trying to find out what the non-stick coating is and whether that would make the aluminum non-leachable. Any ideas on that?
Have you tried the Reynolds SlowCooker liners? I LOVE them! It would give you a barrier between your food and the slow cooker. If you decide to try them, I've discovered that they don't work very well with your setting on high--it gets too hot for the liner. Low to medium works great though. They make cleanup so much easier.
Yes, one of the advantages of this particular model is that you can place the cast aluminum insert right on the stovetop to braise or brown food before beginning the crockpot-type cooking. Thanks for the thought, though!
