Consider baking sweet potatoes for a healthful side dish at home. Select fresh ones that have smooth skin, and are free of cracks, soft spots or blemishes. Like other potatoes, you can store them for at least two weeks in a cool, dark place.

Bake several at once to have for leftovers later in the week. Unlike white potatoes, sweet potatoes remain creamy and soft after cooking. They also reheat nicely in the microwave. To bake them at home:

Heat oven to 400 degrees. Wash and dry the potatoes. Pierce each potato several times with a fork. Place potatoes on a baking sheet covered with foil, on the middle rack of your oven.

Bake for 40 to 60 minutes. Cooking time varies based on the potato size. They're done when you can stick a fork into the center easily. If the potatoes are very large, halve them.

Baked sweet potatoes are yummy plain. Or add just a teaspoon of margarine or butter for a little flavor. Remember, adding extra fat or sugar starts taking away from the healthful benefits of that sweet potato.

Many recipes call for medium-size sweet potatoes. Some in the grocery store are huge. For cooking purposes, 1 pound of sweet potatoes equals about three medium whole, 2 cups mashed or 3½ to 4 cups chopped.
