Roast Beef - 1970's (Marguerite Patten)

So you think you know how to Roast Beef?  You haven't Roasted nothing until you've done it Patten-style.

If you scour the internet, you can most probably find a recipe on how to do a good roast, however it doesn't say anything about how your mum would do a roast.

There are so many many variations on this classic, my Dad does it completely differently from my Mother-In-Law for instance.  But this, dear reader, is the control method.
