Hey, Robert I don’t think it was necessary to swap tomato juices with white wine in a seafood stew. If it is a seafood stew you could have added vegetable stock or the codfish stock in place of white wine.
I think it is not enough to saute onions and garlic, a dash of herbs could have increased flavors. Robert your fish stew is great with tangy and acidic tastes , but a bit overdone with White wine and Worcestershire sauce. White wine pairs best when the seafood is grilled or simply sauteed with seasonings and sauces. Thanks Robert
