  1. I used light sour cream.
  2. You could also use mild or sharp Cheddar cheese instead of extra sharp Cheddar cheese.
  3. The reason that you want to pierce the potatoes with a fork is to allow the steam to escape. Otherwise, the potatoes could explode during cooking. I can personally attest to the exploding potato and resultant mess!
  4. You could also microwave the potatoes rather than baking them in the oven.
  5. If you prefer, you can actually leave the skins on the potatoes. In this case, cut up the potatoes and mash with the other ingredients.
  6. If prepared in advance and refrigerated prior to baking, allow an extra 5 minutes or so in the oven.
  7. Leftovers can be reheated for several minutes in the microwave, or in a 350°F oven for 15 to 20 minutes.
