Step 1

Put the pork in a roasting tin, tip over all the marinade ingredients and massage it in with your fingers (or use a spoon) to coat the pork. Cover and chill overnight.

Step 2

Heat oven to 160C/140C fan/gas Cover the tin with foil and cook the pork for 31/2 hrs, basting every hour. Increase the oven temperature to 180C/160C/gas 4, remove the foil, baste the pork and continue to cook for 45 mins until it is beginning to caramelise around the edges.

Step 3

Remove the pork from the tin and set aside to rest for 20 mins. Meanwhile, spoon away any fat from the tin and transfer the sauce to a small pan. Slice the pork – it will fall apart as you cut into it – then return to the tin. Warm the sauce in the pan, then pour over the meat and toss everything together. Spoon into the hot buns with the Pickled carrot & mooli, spring onions and a dollop of wasabi mayonnaise.
