Heat the oven to 160c/fan 140c/gas 3.
Mix the soy, vinegar, honey, spices and rice
wine and tip into a shallow baking dish that
will hold the pork snugly. Add the pork and
cover the dish with foil. Cook for 21/2 hours,
adding a splash of water if the sauce looks like
it might evaporate. Take the foil off and turn
the oven up as hot as it will go to crisp the skin
and reduce the sauce. Keep an eye on it so it
doesn’t burn, it will take about 30 minutes.
Meanwhile steam the greens and drizzle
with a little sesame oil. Slice or cube the pork
and serve it with the greens, steamed rice
and the sauce spooned over.
