Don’t bake sweet potatoes as well as cured ones, as fresh ones are more starchy than sweet, and you should resist the temptation to dig and immediately eat sweet potatoes. If you wait at least three weeks before eating, the starches will convert to sugars. If stored in a cool, dry place, sweet potatoes can last six months or more.
