This dish is, simply put, an extremely easy one-pot fish/seafood meal. In addition to flexibility in ingredients, the recipe can be stretched (or shrunk) with little concern for adjusting any individual quantities. Serve with fresh or cooked vegetables or boiled potatoes. Pass around fresh lemon for drizzling.
Seafood. Use firm white fish like fillet of cod, haddock, or pollack. To add color and flavor, include some salmon and/or small shrimp or scallops. Remove skin and any bones from the fish fillets, pat dry with paper towel, then cut into bite-size pieces. Peel shrimp.
Dairy. The recipe lists whole milk mixed with sour cream, but you can substitute other dairy combinations such as all half-and-half or whole milk with softened cream cheese. Avoid low-fat milkthe dish will be unappealingly soggy.
