Poached Fish with Russian Sauce
“Russian Sauce” is probably the origin of Russian dressing, though the two no longer have much in common; still, the pickles and capers mark the relationship. This is most traditionally made with sturgeon (which is a wonderfully sturdy and flavorful fish) but can be made with any firm white fillet, from carp, catfish, or sturgeon to red snapper, sea bass, or grouper. Serve with boiled potatoes or plain white rice.

Ingredients
Preparation
Step 1
Put the oil in a deep skillet and turn the heat to medium-high. A minute later, add the mushrooms and onion and cook, stirring occasionally, until softened, about 5 minutes. Add the tomatoes and cook until they break down and release their juices, about 10 minutes. Stir in the olives, pickles, capers, stock, and salt and pepper and bring to a steady simmer.
Step 2
Sprinkle the fish with salt and pepper, then gently slide the fillets into the stock and cook just until a thin-bladed knife passes through with little resistance, less than 10 minutes. Transfer the fish to a warmed serving dish.
Step 3
Bring the sauce to a boil and reduce slightly. If you want a thickened sauce, as is traditional, mix the cornstarch with 2 tablespoons cold water and stir into the sauce. Lower the heat, then simmer until the sauce thickens; taste and adjust the seasoning. Spoon the sauce over the fish, garnish with parsley, and serve.
