The beauty of buying pork neck with the skin on is that you end up with a braised piece of meat topped with a lovely piece of crackling - the best of both worlds. This sauce is quite rich and would be good paired with a crisp bitter leaf salad and some mashed potato.
Note Allow plenty of time to rest meat so the proteins relax and the juices settle. It really makes the difference for a juicy, tender result. Cover the meat loosely with foil (unless it has crackling, which would lose its crunch) and rest it in a warm place. Large cuts of beef, veal and pork need around 30 minutes, chicken 15 minutes and fish 5-10 minutes.
