1. Mix together sage, parsley lemon zest and crushed garlic cloves in a bowl. You should get something that resembles a thick paste.

2. Spread the herb mix all over the pork and place in a slow cooker.

3. In a jug mix together the apple juice with veg stock and then pour over and around the pork. Place the lid on the slow cooker and cook for 4.5-5 hours on high.

4. When the time is up, remove the pork and slice (if it doesn't fall apart!), pour the apple juice, stock and any juices from the pork into a saucepan and place on a low heat. Add 1tbsp cornflour mixed with a drop of water to the liquid and stir until it thickens. Pour over the pork and serve.
