You make sweet potatoes by washing whole tubers, piercing their skins with a fork, and baking them at four hundred degrees Fahrenheit for forty five minutes until tender. Alternatively, you can peel and dice the sweet potatoes into cubes, toss them in olive oil and spices, and roast them on a baking sheet until caramelized. Boiling cubed sweet potatoes for twenty minutes also allows you to mash them with butter and milk for a creamy side dish. Each method highlights the natural sweetness and versatility of the root vegetable.
