Sweet potatoes

Look: Even, deep-colored skin free of gouges, sunken spots or dark shoulder bruises.
Feel: Hard and heavy for its size from tip to tip — soft ends are the first sign of spoilage.
Smell: A sound root barely smells at all; any fermented or moldy whiff means trouble inside.
Tip: Ask if they have been cured — freshly dug roots need a week or two of warm curing before the sweetness really shows up.
Keeps: Cool, dark pantry, never the fridge; cured roots keep a month or more.
