Here are some tips to keep you whipped potatoes light and heavenly.

1. Always heat the milk and butter before gradually adding to the potatoes. 

2. Whip with a potato masher or and electric mixer.  (Food processors turn potatoes into a thick, gluey mixture.)

3. For fluffier potatoes, use an up and down motion with a potato masher, instead of a stirring action, to incorporate more air.

4. Instead of traditional butter and milk, consider stirring in chopped sun dried tomatoes, light sour cream, chopped basil, grated cheese or garlic oil.
