Diana Henry's roast pork with juniper, rosemary & cider

1 Lay the pork on a board, flesh side up. Make a slit down the centre of the meat approx 2-3cm deep. Then, with the knife horizontal, cut a little way towards the outer edges, opening up the pork. Make incisions all over this with a sharp knife and push the slivers of garlic into them. Roughly crush the rosemary and juniper berries with sea salt flakes and pepper in a pestle and mortar, then gradually add the olive oil. Transfer the pork to a roasting tin (that will fit in your fridge). Rub the pounded mixture all over the meat, pushing it down into the incisions. Cover with clingfilm and leave in the fridge overnight.

2 Bring the pork to room temperature before you want to cook it. Preheat the oven to 220°C, gas mark 7. Roll the loin and tie it at intervals with kitchen string. Season the skin well with sea salt. Roast for 15 minutes, then turn the heat down to 180°C, gas mark 4 and cook for 1½ hours, basting every so often. Transfer to a warm serving platter (or a tray with a lip). Cover with foil, insulate (I use old tea towels) and leave to rest for 15 minutes or so.

3 Set the roasting tin over a low heat and add the cider. Heat, scraping to dislodge all the bits stuck to the base. Pour into a glass jug and add a good handful of ice cubes – this will drive the fat to the surface. Lift the fat off with a spoon. Strain and return the skimmed mixture to the roasting tin. Boil until reduced by half. Add the stock and boil until you have juices that are the consistency and depth of flavour you like (it doesn’t have to be thick – well-flavoured juices are what you’re after).

4 Carve the pork and serve with the cider gravy and the fennel. Mashed or little potatoes roasted in olive oil would be good on the side.
