Yeah, the back of the finger is key. I do something like that at work all the time with cold glassware, just a quick touch to see if it's actually chilled. Same idea here. That split-second check saves you a world of hurt. It's wild how the simple tricks from one job, like cooks tapping a pan, translate so well to another, like not grabbing hot steel. You find yourself doing that quick brush check on other stuff now too, right?
