Use a strainer on top of a measuring jug or a bowl to strain the pork from the wine, allow it to strain for about 5min so that less liquid comes in contact with the hot oil when you fry it. You will need to keep one cup of the soaked wine for later.
Heat the oil on a medium-high heat and fry the pork on both sides, it usually takes about 20min. My frying pan (30cm) was big enough to do this all at once. If not then fry them in batches.
Once the pork is fried on all sides, reduce the heat to medium and add the pepper, ground and crushed coriander. Let them cook for 2-3min or until the coriander becomes aromatic. Add 1 cup of the reserved soaked wine and 1 - 1½ cup of warm water.
Reduce the heat to low, cover the pan and let it simmer for a further 30min or until most of the liquid has evaporated. You may choose to add more crushed coriander seeds and parsley before serving.
