Wash and scrub potatoes; dry with absorbent paper.
If desired, rub with fat for softer skins.
Prick with a fork.
Set potatoes on oven rack or baking sheet and bake at 400Â°F 45 to 60 minutes, or until potatoes are soft when pressed with fingers (protected from heat by paper napkin).
Remove from oven.
To make potatoes mealier, gently roll back and forth on a flat surface
