Combine the salmon in its liquid with the rest of the ingredients, except the oil, in a large mixing bowl.
Roll into balls and fry in hot oil until golden brown.
Serve with sweet and sour sauce (see below).
Sweet and Sour Sauce
Blend all the ingredients into a smooth sauce and bring to the boil over medium heat or just until it thickens. Check for sweetness - if too sweet add a little more lemon or vice versa.
To make it a little fancier, add drained mandarins and crushed pineapple to the sauce.
Serve with the fishcakes.
