A premium monkfish liver (ankimo) dish that completely eliminates fishy odor using the chef's secret low-temperature cooking method, maximizing a buttery, smooth flavor.

Monkfish is salted to remove its fishy odor, then simmered in sake and water until the liquid is reduced. Green onions and butter are added to enhance the flavor, creating a Japanese-style braised monkfish dish with a salty broth.
