Hi maxd,
If you have any dripping over that has the rich brown gravy/jelly at the bottom, make sure that this is always covered with the 'fat' part of the dripping.
Like catso has said about his goose fat from Christmas (I used all mine up cos I love dripping toast ! - but having another goose at Easter have replenished the dish), it really can last a long time. Don't forget to use it for all other cooking: Yorkshire puds, Toad in the Hole, basting other roast meats, bacon and eggs, any 'fry up' * if cholesterol isn't a problem*
Even rubbing on your chest when you have a chest cold !! Lol And of course, as said before, dripping toast.
Had to put in the *disclaimer*, otherwise the fat police will cause a riot.
Enjoy !!
