I plan to grill beef burgers and hot dogs 2 or 3 hours before they will need to be served. Would a crockpot at the "Keep Warm" setting be suitable for keeping them at a proper temperature for food safety and also warm enough for serving. If so, would I need to add anything to the crockpot to keep the burgers and hot dogs from drying out? And if there is a better way to accomplish this, please pass any ideas along. Thanks.
