Bring a saucepan of water to the boil, season with salt and boil the pork ears for 30-40 minutes. Remove from the water, transfer to a bowl and let cool.
In the meantime, chop the garlic and roughly chop the coriander leaves. Cut the cooled pork ears into bite-sized pieces. Season with salt, coriander and garlic to taste and place in a bowl with a lid and mix well. Add the vinegar and oil and mix well again.
Close the bowl with the lid and let the salad stand in the refrigerator for at least 3 - 4 hours. The longer the salad draws, the more aromatic it becomes.
