Lumps of Beef Never cook well. (imho

KaHn, that looks awesome.
Thanks for the tips all! Progress update...
I've gone for the searing then slow roasting on a trivet of veg (1 x onion, 1 x shallot, garlic, 2 x carrots). Could have done with more veg, but that's what was in the cupboard.
I put the oven on 200 and roasted the veg with some olive oil for ten minutes.
It's been sitting on the side for an hour to get to room temperature. I rubbed sea salt, pepper, and garlic into the meat, pressing bits of garlic into the gaps in the meat.
Then I got a heavy pan really hot with some vegetable oil and seared the outside of the beef for about a minute on each side. (The fried egg is for a bacon and egg roll

).
Then I put an oven thermometer into the thickest part and decided that, since bacon never fails, I would use the two spare rashers I had hanging around to protect the meat somewhat and add some flavour.
The oven's on 100 degrees C. When the meat is at 60 degrees in the middle, out it comes to rest while I make the gravy (got some concentrated beef stock ready to go).
See you in ~ three hours!
