Kish’s version gets rid of the Filet-O-Fish’s sandwich element, instead opting for a light, fluffy "bun" made out of phyllo dough and dill. For the fish itself, Kish uses steamed black bass, and rather than cheese and tartar sauce, Kish uses crème fraîche and a “brioche sauce” made by combining toasted bread cubes with simmering thyme, cream, and milk in a blender.
