Cabillaud Salé, or Morue à la Hollandaise

Cabillaud salé, ou morue à la hollandaise (salt cod with parsley, potatoes, and melted butter), teaches the gentlest lesson in fish cookery: the water may approach a boil, but through the ten-minute poach it must only tremble. Boiling tightens cured cod into dry little flakes; quiet water lets it open into moist, pearly leaves.

The entry calls on Sole à la Hollandaise (No. 829) and assumes a deep fish dish, a service napkin, and enough hands to land the potatoes and melted butter beside the fish at precisely the right moment. It asks for no saucier, stockpot, or salamander. At home, a wide lidded pan, two ordinary saucepans, and a clean towel do the work. This version keeps the cold-water start, covered ten-minute poach, parsley ring, plainly boiled potatoes, and exact two ounces of butter. The cod is merely divided into thick portions so it fits a home pan, and the wet service napkin becomes a brief drain on clean cloth before the fish reaches its platter. One cook, one stove, one evening, once the soaking is done.

Desalting is the preparation that decides everything before heat enters the matter. Test a small cooked flake rather than trusting the clock, and if the salt still stings, return the cod to fresh water for a few more hours. After that, guard the barely trembling poach. That is the dish.
