I'm tired of cold plates at Thanksgiving. By the time we get everything on the buffet, some of the food isn't terribly warm (we use warming plates for some, but not all, of the food -- for example, we don't keep the turkey warm because it dries out) and to put the food on cold plates compounds the problem. What do you use to warm up plates? In the past we've run hot water on them -- that works, but they cool off quickly. I've seen the plate warmers at http://www.platewarmer.com/, but I don't know if they are any good. I didn't see anything on Amazon.
