The thermal mass retains heat very well. You don’t get as much of a drop in temperature when adding a bunch of cold ingredients. Plus, the pans are nearly indestructible so even if you burn something, it really doesn’t matter. It just takes some elbow grease to get it off. I can cook a pretty darn good steak in these pans when I’m feeling lazy.
I suggests using a well-used soft sanding pad like this one. You get much better control, and don’t have to worry as much about grinding too deep.
