I have a bad cheap cooktop that doesn't heat evenly which is a secondary thought because I do have cast iron and heavy stainless pans to use. My real quest is to find a "flame tamer" or whatever you want to call it for use on a camping stove that is a bit of a blow torch. I'm not looking to cook gourmet meals but, I also don't want a have scorch marks and raw ingredients either.
I think I want an aluminum disc a ~1/4" thick but, I am receptive to other materials as well. The smallest I need is a 5" diameter and the biggest is 7".
TIA,
Sid
