Lightly crush the fennel seeds with the leaves from the thyme and the garlic in a pestle and mortar. Add 1 tbsp oil and plenty of salt and pepper, then bash to a rough paste. Rub all over the pork, then cover and chill for up to 24 hrs, if you have time (2 hrs if not).

Set your slow cooker to a low heat. Pour a kettleful of boiling water over the shallots, then set aside for 2 mins until cool enough to handle – this will make them easier to peel. Cut off the root and remove the papery skins. Heat the remaining oil in a large casserole or frying pan large enough to fit the pork. Brown the shallots for a few mins then tip into the slow cooker. Add the celeriac and apples, season well and give them a mix.

Brown the pork in the same pan, on all sides, not forgetting the ends. Sit on top of the veg and apples, fat-side up, nestling the joint in a little so you can fit the lid on. Pour the wine into the frying pan and bubble for a minute, scraping the bottom of the pan to pick up any tasty bits. Pour in the stock, honey and mustard, bubble for another min, then pour over the pork. Cover with a lid and cook on low for 5-6 hrs (depending on slow cooker size), turning the pork and stirring the veg halfway through cooking.

Remove the pork, wrap in foil and leave to rest for 10 mins before carving to serve alongside the veg with roast potatoes and greens.
