We have goose, rather than turkey, so I make stock from a couple of roast duck carcasses, and simmer the giblets from the goose in that, on Christmas Eve, add port, and redcurrant jelly, then cook it down and add a paste of butter and flour to thicken it.
I am not a fan of gravy - my mum hates it, so we never had gravy on roast dinners (we did have bread sauce, apple sauce, mustard or parsley sauce, depending on what the joint was), so I grew up used to gravy-less dinners. Usually, if I make a roast, I make some gravy from gravy granules, for dh and any dses that happen to be at home, and I have it without, but proper gravy, made with the stock and all the added faffing is pretty nice, so I do have some on my Christmas dinner.
Not too much, though, and nowhere near the roast potatoes, because I don’t want the crunch to go soggy!
