Sweet Potatoes
Sweet potatoes are starchy, naturally sweet root vegetables with orange, white, or purple flesh, roasted, mashed, fried, and baked across American, Southern, and many global cuisines.
How to buy
Choose firm, smooth-skinned tubers without soft spots, cracks, or sprouting; small to medium sizes tend to cook more evenly than very large ones.
How to store
Keep in a cool, dry, well-ventilated pantry spot, not the fridge, where cold temperatures turn the starch texture unpleasant; stored this way they keep for several weeks to a couple of months. Cooked sweet potato keeps refrigerated for about a week.
Culinary profile
- Flavor
- Naturally sweet and earthy raw, intensifying significantly with roasting or baking as sugars caramelize; boiling mutes the sweetness compared to dry-heat cooking methods.
- Texture
- Dense and starchy raw; roasting yields a soft, almost custardy interior with caramelized edges, while boiling or steaming gives a smoother, moister mash.
- Aroma
- A mild, earthy, faintly sweet smell that turns richer and more caramel-like once roasted.
How to prepare
- Roasted — Halved or cubed and roasted until caramelized outside and tender inside.
- Mashed — Boiled or baked then mashed, often with butter and warm spices.
- Fried — Cut into fries or chips and deep-fried or baked until crisp.
- Steamed or boiled — Simmered whole or cubed for a softer, milder result.
- Candied — Cooked slow with brown sugar and butter into a sweet, glazed side dish.
