Martha shows how to make a baked potato, No. 8 in our 20 More Things Everyone Should Know.
Preheat oven to 400 degrees. Line a baking sheet with parchment paper. Insert a metal skewer lengthwise through the center of each potato. Place on baking sheet and bake until tender when pierced with the tip of a knife, about 1 hour.
Remove from oven and break open by smashing on counter, or breaking in half. Top with desired toppings, and serve immediately.
