Measure the cayenne pepper, paprika, cumin, garlic and salt into a jar, screw on the lid and shake everything together really well.
Toss 2 lean lamb leg steaks in the juice of 1 lemon and set aside in a non-metallic dish for 3-4 minutes. Sprinkle each side of the steaks with 1tsp of the spice mix, rub it into the meat and marinate for 2-4 hours. If you’re pushed for time and can’t leave it this long the spice mix will still work but will be a little fiercer. To cook, smear the meat with the olive oil and griddle or barbecue for 3-4 minutes on each side
