I will be making good old fashioned mashed potatoes tomorrow for a church meeting (which is taking place at my house). We are going to have dinner together as a group after the meeting. The meeting will last an hour, then we will eat. The food should be ready to eat as soon as we are done with the meeting. I was going to make mashed potatoes, but can't figure out a good way of keeping them warm. A crockpot perhaps? The oven? Any ideas?
