Marinate the steak in the 20ml of olive oil and Worcestershire sauce. Season liberally with salt and pepper and cook to the desired degree over hot coals.
Remove the steak from the heat and leave to rest. While the steak is resting put a large blob of Masala butter on top of the steak.
Grill the red onion rounds until soft and charred, season with salt and pepper and then dress with oil and vinegar and finally mix together with rocket. Serve the salad alongside the rested steak.
Fry the finely chopped onion and garlic in a little olive oil until soft and translucent. Add the curry powder and fry for a couple of minutes. Place the onion mix with the rest of the ingredients into a blender and blend to a rough paste. Add the butter and blend till evenly mix.
Season to taste.
