How do I bake a yam?

1. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius).
2. Wash the yam and pat it dry.
3. Prick the yam all over with a fork. This will help the yam to cook evenly.
4. Rub the yam with olive oil. This will help the yam to brown and prevent it from sticking to the pan.
5. Place the yam on a baking sheet and bake it in the preheated oven for 45 minutes to 1 hour, or until the yam is tender.
6. Let the yam cool for a few minutes before slicing it open and serving.

Here are some tips for baking a yam:

- To test if the yam is done, insert a fork into the center. If the fork slides in easily, the yam is done.

- If you want the yam to be more caramelized, you can brush it with honey or maple syrup before baking it.

- You can also add spices to the yam before baking it, such as cinnamon, nutmeg, or ginger.

- Yams can be baked with other vegetables, such as carrots, potatoes, or onions.

- Baked yams can be served as a side dish or as a main course.
