step 1
Into a food processor put the garlic, ginger, lemongrass, spring onion, chilli, coriander and the tbsp oil. Pulse until it is well chopped up.
step 2
Add the fish, fish sauce, salt, lime zest, sugar and egg and whizz until it forms a smooth paste. Scoop out into a bowl and, using your hands, pick up the mixture and repeatedly through it against the side of the bowl. Do this for 3-4 minutes (this thickens and aerates the mixture). Chill the mixture for 15 minutes.
step 3
Shape into little patties and shallow fry for a few minutes on each side until golden and cooked through.
