Get a nice big gammon/ham.
Roughly slice up some apples and put them on the bottom of the roasting dish. Stick the gammon/ham on top and poor over about 1/2 pint of cider. Top up during cooking and baste with the lovely hot cider. When cooked mush up the apples with the cider and make a rustic boozy apple sauce. Might want to cover with foil early on in the cooking.
mmmmm, cider infused warm ham for dinner with lovely apple sauce, then for lunch and then ham, eggs ‘n chips the next night if you have any left.
edit: also works with belly pork, shoulder etc etc. But remember the crackling.
