Ha! I actually wrote it down! Here goes....
2 big sticks of celery
Two big carrots
2 Onions
Dont peel! but chop roughly.
6 leaves of sage, some rosemary and bay leaves
2 rashers of bacon, chopped
Chicken wings (didn't get the quantities but looked about 8 to me) bash those with a heavy knife,
2 star anise
then put the lot in a roasting pan and roast for an hour at 200c.
Squish in the tray, then (here my notes are a bit skimpy) put water in, I think to cover, but certainly two pints with this amount)
cook for 20 mins.
sieve, making sure you squish all the good stuff out.
It can be done to this stage in advance. Come dinner time, mix with the turkey juices (after having removed excess fat) and mix in two tablespoons of cranberry sauce.
I think there might have been some flour added after the first squishing, but that is the only hole in my notes.
Hopefully you can remember the gaps and tell me!
