Notes
Pierce them, every time. Four or five holes let the steam escape. Skip this and a sweet potato can split open in the oven, or burst outright.
Dry them properly before oiling. A wet skin steams rather than roasts, and you lose the crisp exterior entirely. Pat them down with a towel after scrubbing.
Size changes the timing. An hour suits large potatoes. Medium ones are usually done around 45 minutes, and small ones closer to 35. They are ready when a knife meets no resistance at all.
Skip the foil wrap. Wrapping in foil traps steam and gives you a wetter, denser potato. Straight on the lined sheet, or directly on the rack, is what makes the inside fluffy.
