Can't wait to see your video, but I saw your steam table pan and had to comment. I always used a round pot until I read Gianiclis's book and there on page 106 she talks about them. I ordered a 2/3 size like yours for about $15 plus shipping and haven't looked back. I now have a collection cause they're so handy. I use the 2/3 for 2 gal batches and a full size for 4 gal. A lot of advantages over round pot, not the least is it lends itself to using a fishing line harp. Pics below show my heating set up and my home-made harp sized for the pan. I've settled on using an electric griddle with a ceramic tile between the pan and griddle surface. The tile acts like a pizza stone and gives the best heat distribution over the hundred or so I tried
. Did some experiments with water and know where to set the controller to get the right heating rate over the cooking interval. Also is low mass, so I know that when I turn off the heat the temperature will rise only 2 deg. so I can account for that.
