Sweet Potato
Flavour Profile
Deeply sweet, earthy and nutty. When roasted, the natural sugars intensify into a caramel-like flavour with a smooth, velvety mouthfeel.
Health Benefits
Sweet potatoes give you beta-carotene, which your body turns into vitamin A. That's good for eyesight and skin. And plenty of fibre, which keeps your gut happy.
Buying Tips
Look for firm, heavy tubers with smooth skin. Avoid any with soft spots, wet patches or sprouts. The smaller ones are often less fibrous and peel more easily than the giants.
Storage
Store them in a cool, dry, dark place with plenty of ventilation. Never put them in the fridge. Cold temperatures change their cell structure, giving them a hard, unpleasant core and a strange taste.
Cooking Uses
Roast them whole in their skins for the fluffiest interior. Mash them with butter and lime for a bright side dish, or cut into wedges for chips. They also hold up well in curries and stews, absorbing spices while providing a creamy texture.
Forkin' Food Theory
Sweet potatoes aren't just orange potatoes. They belong to a completely different plant family.
While a regular potato is a tuber, a sweet potato is an overgrown storage root. This is why they behave differently in the heat.
The sweet potato contains an enzyme called amylase. When you heat the root slowly—like during a long roast—this enzyme breaks down its complex starches into maltose.
High heat isn't just about browning; it's a chemical conversion that literally makes the vegetable sweeter as it cooks.
