As requested:
Trim a tenderloin of all fat and as much silvering as you can, then brine for about an hour and a half in an 80% solution.
(80% brine:- 265g of sea-salt and 50g of good brown sugar per liter of water, plus a few peppercorns and cloves, a stick of cinnamon and some lemon peel. Boil for a few minutes, then chill before use.)
When the brining time is up, hang the pork in the fridge for 24 hours to dry and for the salt-glaze to form.
Cold smoke too taste. I found 24-36 hours is a good compromise between moistness and smokiness. My wife prefers the lower end of smoking time, and my father would like it if I smoked it until the loin was the same size as a pencil, so do some experiments. I use beech chips, BTW.
Serve sliced thinly with mustard and good pickles on rye bread, or tossed into hot pasta with a bit of cream, pepper and some chopped capers.
