Place the fish, cream, egg, flour and wild garlic or chives in a food processor. Season with salt and pepper and using the pulse button, process to combine the ingredients. Be careful not to over mix or the texture will be too smooth and loose its charm. Add the capers and mix in very briefly.
Divide the mixture into 12 little patties and with lightly floured hands, shape into neat round cakes. Chill until ready to use.
To cook the fish cakes, divide the butter and oil between two medium sized frying pans or one large one. When the fat sizzles, add in the cakes leaving a little space between them. Cook the cakes over a medium heat for 4-5 minutes on each side until golden brown and cooked through.
Serve the cakes on hot plates with lemon wedges, a salad of foraged leaves and horseradish Mayonnaise.
