How to Choose Sweet Potatoes

When purchasing fresh sweet potatoes, look for firm, smooth-skinned potatoes without any soft spots, sprouts, or signs of decay. The skin should be even in color and the potato should feel heavy for its size. For canned, pureed, or frozen sweet potatoes, choose brands with minimal added ingredients to maintain the natural flavor of the sweet potatoes. Always check the expiration date and packaging integrity.

Cooking/Prep Tips for Sweet Potatoes

Sweet potatoes are a versatile and nutritious ingredient that can be prepared in a myriad of ways. For intermediate and expert home cooks, it's important to note that the high sugar content of sweet potatoes can lead to quicker caramelization, which is excellent for creating a sweet, crispy exterior but can also cause burning if not monitored. To achieve an even cook, it's often beneficial to parboil sweet potatoes before roasting or frying. When baking, piercing the skin can prevent bursting and allows steam to escape. For mashing, cook sweet potatoes until they are very tender to ensure a smooth texture.

Shelf Life of Sweet Potatoes

Fresh sweet potatoes should be stored in a cool, dry, well-ventilated area away from light, which can cause them to sprout or spoil. They should not be refrigerated raw as cold temperatures can affect their taste and texture. Canned sweet potatoes should be stored in a cool, dry place and once opened, transferred to a sealed container and refrigerated. Pureed, frozen, or dried sweet potatoes should be stored according to package instructions, typically in a cool, dry place or frozen until ready to use.

Cooking Techniques for Sweet Potatoes

Grilling: Grilling gives sweet potatoes a smoky flavor and charred exterior. Slice them into wedges or rounds, brush with oil, and grill over medium heat, turning occasionally, until they have grill marks and are cooked through.

Roasting: Roasting sweet potatoes intensifies their natural sweetness and creates a crispy exterior. Cut them into even pieces, toss with oil and seasonings, and roast at 425°F (220°C) until tender and caramelized, usually about 25-30 minutes.

Steaming: Steaming is a healthy way to cook sweet potatoes without adding extra fat. It preserves their color and nutrients and results in a tender texture. Steam whole or cut sweet potatoes in a steamer basket over boiling water until they are soft.
