Fish Cookery: The Internal Temperature Paradox

Fish cookery temperature is the single most contested area in professional kitchens — the traditional doneness tests (flaking, opacity) produce overcooked fish by the standards of modern fine dining, while the modern target temperatures (45–50°C internal) produce fish that appears raw to trained eyes conditioned by traditional techniques. This entry synthesises the positions of López-Alt (Food Lab), Modernist Cuisine, and classical French technique to produce a complete framework.

A framework for understanding fish doneness at different target temperatures — each producing a legitimate texture outcome, with the correct target depending on the application and the diner's preference.

• Japanese sashimi (raw — 0°C internal, the extreme end of the spectrum), Scandinavian gravlax (salt-cured raw — similar temperature but different preservation state), French sole meunière (60°C target
