Roasted Sweet Potatoes

I don't actually know the difference between sweet potatoes and yams, but according to my mom, who's perfected this recipe over many years, YAMS are more delicious.

• Scrub yams and poke holes using a fork
• Place yams on a cookie sheet lined with aluminum foil
• Cook at 400°F until yams are soft (about an hour)

Serve with brown sugar and butter.
