A large beef roast is the simplest of all party entrees to prepare well. Select it carefully and cook it right and you will hear nothing but praise from your diners.

I wanted to find out if 2 roasts (e.g. 6 pounds each) takes the same amount of time to roast as a single roast (e.g. 12 pounds).
The answer is: a bit more time than it takes for one.
I have 2 of unequal size. The meat thermometer checks the smaller one first.
Phooey – combine the 2 weights then compute as a single roast. I guess if I had 56 lbs. of roast it might be different. A 7 + a 6 took the same time as a 13.
