Fishcakes are just cooked fish mixed with mashed potato and then fried, yes? Well every single time I do them they just disintegrate in the pan and are so sloppy that they don't hold their shape. I don't add any liquid so I have no idea why this happens. I've tried coating them in breadcrumbs, adding oatmeal to dry the mix up a bit, adding egg yolk to bind it - but nothing makes a difference. We end up calling the fishcakes Tuna Splat
