How to make Black Cod with Mushrooms and Sansho Pepper

Bring water, soy sauce, mirin, sansho pepper, shallot, and one third of garlic to a boil in a 1- to 2-quart heavy saucepan, then simmer 5 minutes. Let broth stand off heat 10 minutes.

Cook remaining garlic in oil in a 10-inch heavy skillet over medium heat, stirring, until just golden. Add all mushrooms and cook, stirring occasionally, until tender, about 3 minutes.

Strain broth through a fine-mesh sieve into mushroom mixture, discarding solids, and simmer 1 minute.

Pat fish dry and sprinkle with 1/2 teaspoons salt and 1/4 teaspoons pepper. Heat oil in a 12-inch heavy nonstick skillet over medium-high heat until hot, then sauté fish, skin side down, turning once, until golden brown, just starting to flake, and just cooked through, about 10 minutes.

Transfer fish to shallow bowls. Reheat broth and divide among bowls, then sprinkle very lightly with more sansho pepper (if using).
