This is great eaten outside (bonfire night?) in a sandwich or floury bap and can even be finished off on the barbeque or (well-wrapped in foil) in the embers of a fire

1. Mix the soy sauce, honey, mustard, ginger and oil to make a marinade and leave the pork to steep in the mixture overnight in the fridge. I have to confess to an unhealthy addiction to crackling and the way to get it good and crispy is to keep it dry (so when marinading the meat, keep the skin out of the liquid.
2. Make sure the skin is scored well, then rub a little sea salt over it, getting between the score marks (wipe off any excess). Begin roasting uncovered in a preheated oven on a high heat (450F/230C/gas 8) for 20-30 minutes, then turn heat down low (300F/150C/gas 2) and continue roasting (cover with foil) for 5 hours.
3. The meat will be tender enough to pull apart with two forks (it is sometimes called pulled pork) and tastes delicious served in a roll or bap with red onion relish or apple sauce

For the caramelised red onion relish:

1. Finely slice the onions and sauté gently until the onions are soft.
2. Add the vinegar and sugar and continue to cook in the pan very slowly for approx. 40 mins until caramelised (gloopy).
