Lay a steak on a chopping board.
Cover with a liberal sprinkling of spice mix.
Tenderize the meat with a fork, this helps to penetrate the meat with the spice mix.
Turn the steak over and repeat on the other side
Repeat this process for all the steaks.
Rub any remaining spice mix onto the outside of the meat.
Place them in the marinating tray.
Cover with oil, (be careful not to pour directly onto the steak as you will wash the marinade off).
Place the tray in the refrigerator and marinate for 36-48 hours.
Remove the steaks from the oil and place them on a rack or anything perforated for 15-20 minutes to allow all the oil to drain off.
Meanwhile pre-heat your barbecue.
Cook steak to your preference.
