What is London Broil and how is it different from other cuts of beef?
London Broil is a type of beef cut that is typically taken from the rear section of the animal, near the round. It is a lean cut of meat, which means it has less marbling and is lower in fat compared to other cuts of beef. This makes it a popular choice for those looking for a healthier option. London Broil is also known for its rich flavor and tender texture when cooked correctly.
One of the main differences between London Broil and other cuts of beef is its thickness. London Broil is typically cut into a thick slab, usually around 1-2 inches thick. This thickness allows for even cooking and helps to prevent the meat from becoming too dry or overcooked. Additionally, London Broil is often cooked using a high-heat method, such as broiling or grilling, which helps to lock in the juices and flavors of the meat.
What is the ideal cooking time for London Broil?
The ideal cooking time for London Broil will depend on the thickness of the cut and the desired level of doneness. As a general rule, a 1-inch thick London Broil will take around 4-6 minutes per side to cook to medium-rare, while a 2-inch thick cut will take around 8-12 minutes per side. It’s also important to note that the internal temperature of the meat should reach at least 135°F (57°C) for medium-rare, 145°F (63°C) for medium, and 160°F (71°C) for medium-well or well-done.
It’s also worth noting that the cooking time may vary depending on the cooking method used. For example, grilling or broiling will typically result in a faster cooking time compared to oven roasting.
