I have people coming over for dinner and I'm doing a roast. I normally use my george foreman roaster but it is broken so I'm going to have to cook it in the oven but have no idea how long to cook it for or on what temp.
I have a vague recollection of cooking it for an hour and then adding 1/2 hour for every 500 grams. Is that right?
But I have no idea what temp. AAARRRGGGHHHH!!!!!!!!

PLEASE HELP ME!!!!

TIA,
Dan.
