Timelapse close-up of a purple-skinned Korean sweet potato roasting on a wire rack inside a black iron drum stove, glowing coals below. The skin slowly darkens and wrinkles, cracks open in one natural jagged split along its length (real baked potato skin, matte and papery), and thick sticky amber syrup oozes out of the crack in small glossy beads and runs down the skin and caramelizes into a glossy dark brown crust, steam rising from the split, the golden flesh showing inside by the final second. The sweet potato itself does not move or roll. Warm orange glow, static locked-off camera. Sound: sizzling and soft crackle, no speech. No text, no logos
