Keep those mashed 'taters warm

Do you ever go to a potluck and want to take mashed potatoes, but just KNOW that they'll be cold when you get there? Well here's a little trick I learned from a friend of mine a few years ago. Mash the potatoes and add the butter, milk, salt, pepper, etc. Put them in the bowl and wrap with foil. Make sure you wrap the entire bowl. Then take a towel, not a dish towel, but a regular bath towel and wrap the foil covered bowl in the towel. This should keep those 'taters warm until you are ready to eat them.
