I have a Westinghouse No r-29 roaster. My brother wants to use it for a large Christmas gathering of his in-laws. Question is water or no water below the drop in container. I've heard both not to use water and definitely use water. They are not cooking in it, just keeping trays of Lasagna warm.
Edit: found the manual, no mention of water. Links: ( interesting recipes)
