I have tried to search for this in old threads without luck. I know it's basic and something I should know but I don't :redface:
Ok. So I have a 650gm topside roastbeef. I have a 600 gas oven (fan forced). I know there's some kind of formula for how many minutes per kg etc but even google is not my friend this afternoon. Can someone please give me some kind of idea how long I should cook this for and at what temperature??
Thanks so much!!!
