Combine fish, 1/2 cup flour, oyster sauce, sweet chilli sauce, fish sauce, brown sugar, coriander, spring onions and egg in a food processor. Process until well combined. Place in a bowl and refrigerate for 30 minutes.
Shape mixture into patties and dust with flour.
Pour enough oil into a wok or frying pan to about 1cm depth. Heat over medium-high heat until hot.
Fry fish cakes for 8 minutes, turning once, or until golden brown.
Easy and tasty, just followed the recipe, except that I didn't put the flour in the food processor with the other ingredients, but mixed it in later. I had the oil a bit too hot at first so they were a little dark but they still tasted good and the second batch was fine. - 10 Nov 2011
