The cookbook author dresses her sweet potatoes twice – first by roasting them in their jackets, then topping them with sour cream and chives

When shopping for sweet potatoes, don’t be scared of soil! A bit of dirt never goes astray, as it acts as a natural barrier to extend shelf life. Select sweet potatoes of a similar size to simplify preparation, particularly if you are planning on roasting them whole like in this recipe, so they all cook through at around the same time.

If your sweet potatoes are on the large size, you might need to roast them for an hour (or you can just chop them into chunky bits to shorten the cooking time).
