Mexico is a part of North America [1]. What is less obvious is whether Guatemala, Belize, Nicaragua, etc, would fall into N or S America. Central America is a region, like the Middle East, but is not its own continent. Central America is a part of North America [2]. Nathan made a good point that the United Nations considers Mexico a part of Central America [3]. I wonder why [4].
Sear each side, flipping minimally. It should not take long for a crisp brown crust to form. Depending on the heat of your pan, it should take about 2-4 minutes (or less) for each side to finish cooking. When the first side is done, flip your steak and cook the second side for about as long.
1 Sear the steak on the side with high heat for 2-3 minutes and then rotate 45 degrees and sear another 2-3 minutes. 2  Flip over and repeat on the other side. 3  Move the steak to the other side of the grill with no heat and close the lid until it is baked to the desired doneness.
