You can now watch how to make a Reduction Gravy in our Cookery School video lesson - Perfect Gravy below.
This recipe is from the Delia Online Cookery School
Firstly tilt the pan so the juices flow into one corner, then spoon off most of the fat from the juices.
Keep the spoon level and be careful not to scoop up any of the meat juices with the fat.
Place the tin over a high heat, then with a spoon, scrape the sides and base of the roasting tin to release all the lovely caramelised bits.
Pour in the wine, cider or stock (or both) and keeping the heat high allow the whole thing to bubble. Turn the heat down to medium and let the gravy reduce until its half its original volume which will take about 10-12 minutes.
Finally, taste and season.
