To make this cabbage in a pan, rub the cut sides of the cabbage with a little vegetable oil. Heat a stainless steel or cast-iron pan over medium-high heat until very hot. Place the cabbage wedges in the pan with one of the cut sides down and cook them for 6–7 minutes, until the side on the pan is deeply browned. Flip and cook the other cut side for another 6–7 minutes. Turn off the heat, add the furu butter, and let it melt over the cabbage.
