Fast and hot. Season the meat with sea salt, black pepper, and garlic powder. Let it sit for 20-30 minutes while you heat your cast iron skillet over medium-high heat with a little coconut oil or lard. It should be looking a little smoky before you place one side on the pan. Let it sizzle and sear for 4 minutes, then turn it over. Cook until it reaches approximately 150 degrees F. Let it rest for approximately 10-15 minutes, then slice against the serve. Serve with fresh herbs and lemon juice.
