To make the marinade, put all the ingredients in a blender and blend until you have a smooth mixture. Put the pork in a large saucepan, pour over the marinade and turn the meat until coated.
For the pork belly, mix the salt, lemongrass, spices, garlic, ginger and red chillies together in a small bowl, then rub the marinade into the flesh side of the pork belly. Cover with cling film ...
Add the chops and let stand at room temperature for 15 minutes. Remove the chops from the marinade. Strain and reserve the marinade. In a large nonstick skillet, heat 2 tablespoons of the oil.
Add water, a little at a time, pulsing to form a thick but smooth paste. Rub paste onto pork, coating evenly, cover with foil and refrigerate 30 minutes. Rinse off paste and pat pork dry.
