In a food processor, combine the fish fillet (you can roughly chop it), the fish sauce, red curry paste, lime juice, garlic, lime leaves and egg white.
Blend until it becomes a paste.
Add the coriander and blend again.
Using your hands, shape the mixture into ten balls and then flatten them into fat discs.
In hot oil, fry the fishcakes on each side until golden.
Place them in a bowl lined with a paper towel to drain.
For the dressing
Combine all the ingredients in a pan.
Set the pan over medium heat on a stove and stir until they are well mixed.
Take the dip off the stove.
Serve the fishcakes on a bed of the salad leaves and with a bowl of the dip.
