Says the guy who thought you measure the heating qualities of stainless steel cookware by looking up the specific heat of stainless steel.
Pointing out the flaws in a certain type of cookware isn't "attacking" it, although this is exactly what I'm talking about with you being so emotionally invested in a pan that you feel it is being attacked and must defend it. Pathetic, much?
The first set shows temperature variance on the pan's surface after 30 minutes. You hate it because you claimed cast iron distributes heat well and are embarrassed at being exposed for being so clueless. The second photos show how cast iron is cooler in the middle because of the burner, because cast iron doesn't distribute heat as well as stainless steel or copper cookware.
I'm going off experiences too, and another poster in here Muhammed noted the same thing where his cast iron didn't heat evenly. You want a real cook? Sean Brock, award winning chef and restaurant owner, who says he loves cast iron pans. From:
THE SCIENCE OF CAST IRON
"That said, a lot of people think cast iron is a good conductor of heat, but it’s actually the opposite, meaning that the pan does not easily give away its heat, especially compared to other mediums such as copper and aluminum. Yes, and that’s definitely a myth that needs to be busted. I think a lot of people have that misunderstanding, myself included in the early days, based off the fact that cast iron can get really hot. That doesn’t mean it’s a good conductor of heat, that just means it can get really hot. And anything can get really hot with a fire underneath it. But a pan also isn’t judged based on its heat conductivity. It’s judged on how well it performs, and that performance is based off multiple properties."
Yes, he's talking about tweedle-dee and tweedle-dum in this forum, who just keep insisting cast iron is a conducts heat well and any photo showing otherwise is part of some vast conspiracy. Lean something, instead of digging in for pride's sake and looking even more stupid.
