Using a meat cleaver split four chops length ways. In a cast iron pan heat some oil, add the trotters and fry until browned.
Add a knob of ginger, a couple of cloves of garlic and a pinch of salt and continue to stir. Add a splash of soy sauce, a tbsp of brown sugar, 100ml vinegar, 150ml pineapple juice and just enough water to cover. Place a lid on the pot an leave to cook for two and a half hours.
When the trotters are cooked, remove the meat and remove from the sauce. Bring the sauce up to a simmer and reduce by half until it forms a syrupy consistency.
Return the trotter meat to the hot pan and smother in the sticky sauce.
