Mix the marinade ingredients in a bowl. Place the steak flat in airtight container.and saturate with the marinade, making sure it covers the entire steak. Seal the container and place in the refrigerator for at least two hours. You can also do this overnight to prepare the steak for either grilling or broiling the next day.
Remove the marinated steak from the refrigerator while you preheat thegrill / broiler. Preheat the oven grill (broiler). Heat a skillet or frying pan on high heat on the stove top. Drizzle a little olive oil on the skillet to prevent the meat from sticking then sear the meat on each side for 90 seconds to contain the juices
Baste with more marinade before transferring the skillet to the center rack of the oven. Use oven mitts, because the skillet will be hot! (If you are using a standard frying pan, transfer the meat to a baking tray in the centre of the oven). Cook for five to eight minutes on each side, turning and basting until the meat is done. Check with a meat thermometer.
