The process of cooking a lean cut of beef, specifically London broil, to an internal temperature of approximately 130-135F, resulting in a reddish-pink center, necessitates careful attention to grilling time. Achieving this level of doneness, characterized as medium-rare, ensures a tender and flavorful outcome. As an example, a 1-inch thick London broil may require approximately 5-7 minutes per side over medium-high heat to reach the desired internal temperature.
Accurately gauging the cooking duration is vital for optimizing the eating experience. Overcooking can lead to a tough, dry piece of meat, while undercooking poses potential health risks. Historically, grilling has been a preferred method for cooking tougher cuts of meat, as the high heat sears the exterior while allowing the interior to remain relatively moist. Proper grilling technique elevates this cut of beef, transforming it into a palatable and enjoyable meal.
