Salting the ribeye steak two days prior to cooking brines the steak, helps tenderize it, and adds rich flavor.
The 48-hour dry brine is crucial; it tenderizes the meat and intensifies flavor by drawing out and reabsorbing seasoned juices. Ensure steaks are thoroughly patted dry before salting and cooking for optimal crust development. A very hot cast-iron skillet is paramount for a perfect sear; don't overcrowd the pan to maintain high heat. Use an instant-read thermometer for precise doneness, aiming for 130-135°F (54-57°C) for medium-rare before resting. Always rest the steak for 5-10 minutes after cooking; this allows juices to redistribute, ensuring a tender and succulent final product. Consider adding a sprig of rosemary or a smashed garlic clove to the butter for aromatic basting during the second sear.
