Anthony Sargeant prefers to fillet all fish himself rather than ask the fishmonger to do it. With John Dory you do need to be careful of the spines but otherwise it is an easy fish to fillet without pinbones. These two lovely fillets were cut by Tony from a medium sized fish. John Dory is one of the very best fish to eat. It is a serendipitous catch – since the Dory does not swim in large shoals and is simply caught along with other fish.
