<human>:  What's the best way to cook a steak medium-rare?
<bot>: The best way to cook a steak medium-rare is to first season it generously with a blend of coarse salt and freshly ground pepper, then heat a heavy cast-iron skillet over medium-high heat. Add a tablespoon of oil and wait until it begins to shimmer. Next, add the steak to the hot skillet and cook for 3-4 minutes on each side, flipping only once throughout the cooking process. Once both sides are cooked to the desired temperature, remove the steak from the heat and let it rest for at least 5 minutes before serving.
