The John Dory (Zeus faber) is a strange, laterally flattened marine fish of the eastern Atlantic, Mediterranean and the seas around Australasia, instantly known by the single large black eyespot ringed in pale yellow on each flank. Beneath its ugly, big-mouthed exterior lies one of the finest white fish in the kitchen — firm, sweet, pearly flesh that holds in clean flakes and is prized from French haute cuisine to the seafood restaurants of Australia and New Zealand.
