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.
Sear steaks over maximum heat: on a charcoal grill, sear 1 minute each side; on a gas grill, sear 2 minutes each side, then reduce heat to medium. Move steaks to indirect heat and continue grilling using the times listed in the chart below. Remove from grill 5Â° before desired doneness and allow meat to rest 5-10 minutes before serving. Juices will be absorbed into the meat and bring meat up to desired temperature.
