My 'secret' is a Gravy Skimmer Jug I've decided. :) Season the meat well, roast high for the first 20 mins then at a lower heat for the rest of the time, adding plenty of oil or butter in the case of leaner meats and basting as you go. Then remove the meat carefully from the roasting tin and allow to rest. Tip the contents of the roasting tin - juice, fat, scrapings and everything - into the gravy skimmer, plus anything that comes off the meat as it's resting, and all the fat will rise to the top. Return a few tablespoons of the separated fat to the roasting tin, place on the hob, and blend with some plain flour until you have a smooth paste, bubbling a little round the edges. Then carefully pour the meat juices into this paste, leaving the rest of the fat behind, stirring constantly. Finally, get your gravy to the right consistency by adding a little vegetable cooking water and/or some wine.
