Remove skin and some of the fat from the pork
Mix this to a cream with some onion, ground pepper, ginger, bay leaves and the juniper berries
Rub this, by hand, well into the meat all around.
Place the pork in the pot to which the red wine and vinegar are added.
Leave this to soak from 5-8 days during which it is occasionally turned (it is best this be kept in the bottom of the fridge)
Remove from marinade- rub with salt and bake in half the liquid
When this liquid has boiled away add the rest gradually
Bake the pork to a good brown color.

Serve 
with conventional gravy and a celery salad (no mayonnaise) and boiled potatoes.

NOTE
The pork will require 3-5 hours cooking time depending on size.
