Indeed, at t=98 it's really clear. I wonder if they tried the pan with no fins under the handle, or with a protrusion to prevent the rising gas heating the handle? Heating the handle to extremes, it seems as hot as the hottest parts, seems like a pretty serious deficiency for a design for domestic use.

I wonder what the beta testing (ie end-user testing) was like. These look like they'd burn your sauce?

Great point. I wonder if a hot handle is at all avoidable when using a more efficient pan.

Comfort is the trade off for efficient cooking.
