I go to a monthly activity which starts with a 5 o'clock pot luck. I like to take hearty hot dishes, and while crock pots are good for soups and stews, not so great for structured casseroles, etc.
What can I use that will keep food warm for a couple of hours in 40-50 degree outside temps? I can make an insulated box myself etc., but want to know if there is something commercially made with power. (Do not want a chafing dish with sterno)
