Heat in oven until crispy and shreddable with a fork, bit like peking duck. Then make a sandwich with a cooked part bake half baguette, add thinly sliced cucumber and a good dollop of hoisin sauce. Poss even spring onions shredded finely.
Sort of pork take on peking duck.
We used to use this recipe for the remains of a shoulder joint that had been braised and then crisped in the oven to get the crackling - used to only just be able to carve it, it was so tender.
We were so greedy, it was only when we had had a huge joint that there was ever any left.
