I did a search and found nothing about this issue on this board.
Ive been going crazy- I can't find the correct term for this sort of thing. You know, when you order enchiladas at a Mexican restaurant, they usually bring 'em out on special plates with a steel liner. The plate-liner was obviously heated in the oven then placed in the plate holder/tray before serving.
I'd love to buy one or two for home-- but for the life of me, I can't find any! Probably because I dont know what this is called.
