George,
2.49? bargin ;D
For me, and this is only my opinion, gas mk 6 is too high.
What I do, I put a large frying pan on the hob, full heat until it's smoking. I then, smear the joint with olive oil, give it a good grind of sea salt, a good grind of black pepper, and sprinkle half a beef oxo cube all over it.
I then sear it in the frying pan, all over until it is well sealed.
I then transfer it to the oven, preheated at gas mk 4 and cook for 30 mins per 0.5kg and 20 mins over. Take out of the oven and let it rest for at least 15 mins.
This method never fails me. It gives me a medium cooked, juicy joint, packed with flavour.
Hope this helps

Ray
