method
1. Put a little butter and oil in a frying pan and very gently cook the onions until they are soft
2. Now put the piece of salmon on top, pour on some white wine, cover the pan with foil and let the salmon cook in its own steam for 3 or 4 mins. Drain the liquid – but keep the onions
3. After the salmon cools a little, mash it with a fork, and add to the mash potato with the onions.
4. Mix everything well, add the chopped parsley and season with salt and pepper to taste. Cover and keep in the fridge for a few hours until completely cold.
5. With floured hands, make small balls (the size of a golf ball), coat with flour, dip in beaten egg and cover with breadcrumbs before deep-frying. Alternatively, flatten the balls with your hands to make small circles and cook them in plenty of hot oil in a frying pan.
6. Serve the fishcakes with hollandaise sauce and a mixed leaf and rocket salad
