I reckon gravy has the power to transform, or even save, a meal. What I want you to do this year is open your mind to a slightly radical idea: making it a few days, or even weeks before Christmas. If you do this, you'll have it on standby, so you can finish it on Christmas Day. I use chicken wings to give the gravy that roasted bird flavour base. Not only are they dead cheap, they're also the most flavourful part of the bird.
