Mix ground pork with curry paste using wooden spoon, then add egg, water, fish sauce, lime leaves and green onion. Mix well. Form into balls, approximately 1 tbsp each, and flatten into 1/2 inch thick patties. Heat oil in a wok add the pork patties and fry over moderate heat until golden. Remove, drain on paper towels and serve with pickled ginger and/or ajad (see below).
Combine the ingredients, and leave to stand overnight.
