Cooking - Help - Beef

[joggerjayne]

I've got this piece of beef.

It needs 20 mins per lb.

It's 12 lbs

12 x 20 mins = 4 hours.

BUT ...

I've cut it in half, and put them in together, in separate oven trays.

Do they now need half the time? because they are half the size?

[joggerjayne]

I just took one bit out. I was going to cover it in foil to help the drying thing.

Does the foil go shiny side in, or shiny side out?

Actually, it already looks done to me.

You can stop your meat from drying out by searing it on all sides to seal the juices in before you put it in the oven. When you roast meat, the outside is cooked first and the juices flow into the middle of the meat if it has been seared properly. When you then take it out of the over and rest it, during the resting time, the juices flow back fairly evenly into the whole roast. This prevents it drying out so much. How long you leave it is also depends on how you like your beef. Rare, medium rare, medium or even done.

[joggerjayne]

Oh. It's too late to do the outside now. I put it in the oven at about half past eleven.

[Carakeel]

sorry, that should have read "out of the oven"

Imagine a cube with 10cm sides. Surface area is 600 sq.cm, volume is 1000cc.
Cut the cube in half, producing two 6-sided solids, 10cm x 10cm x 5cm. Volume of each is 500cc so total volume remains 1000cc. However, surface area of each solid is 4(10 x 5) + 2(10 x 10) = 400sq cm, giving a total surface area of 800sq.cm. So although the volume remains the same, the area has increased by a third. That's why it makes such a difference.

But tinfoil will help.

Hello, Trim.

[joggerjayne]

I've done the tin foil now, vallaw.

[Carakeel]

I'm sure it will be delicious JJ. Enjoy!!

"I'm sure it will be delicious JJ"

You've clearly never had a meal that I've cooked, Carakeel.

I'm not confident about "delicious". I'll be happy with "edible".

[joggerjayne]

Well ... half way there !

[joggerjayne]

Well, I've just poked the beef with my previously unopened thermometer.

Near the outside it's 66 degrees.

In the middle it's 38 degrees.

That seems like quite a big difference to me.

I'll take it as it comes JJ. Get the Yorkie Puds on about 2 and I'll be over about 2.20pm with a bottle of red. Mmmm I can smell it from here.

[joggerjayne]

Was the beef tasty. How many did you have for dinner, a 12 lb piece of beef seems an awfully big joint ;-)
