You prepare a sweet potato by washing the tuber under cold water, trimming away any blemishes, and slicing or dicing it depending on your recipe. Whether you choose to bake it whole, boil cubed pieces, or roast wedges in the air fryer, preparation always begins with proper cleaning. Piercing the skin with a fork before heating allows internal steam to escape safely without causing the potato to burst. Following these simple preparation steps guarantees a tasty and perfectly cooked dish.
