I've only ever managed to make this work once.
He says to stand the roasting meat on a trivet of roughly chopped veg (carrots/onions/celery etc) then once the meat is cooked you remove it to rest and mash up the veg and juices as a basis for making gravy on the hob.
I have two problems with this:
- The veg burns and goes bitter in the roasting pan-->nasty gravy
- no juices meaning I have to basically make a gravy from stock/wine/granules
WHY??
I want to get this right in time for large number catering at Christmas...
