Fish stock, also called fumét in French, is a magnificent base for making soups, chowders, seafood risotto, and any number of sauces. But you may shy away from making your own stock because it is disproportionately labor- or time-intensive. You are not wrong when it comes to beef, veal, or poultry stock, but fish stock happens to be the exception. Unlike chicken stock or beef stock, fish stock is quick and easy to make; rather than simmering away for hours, requiring continuous skimming and fussing, fish stock takes just 45 minutes on the stovetop. 

Although certain recipes will use chicken broth instead of fish stock, such as a simple clam chowder, using the fish stock will really enrich the seafood dish and bring a complex level of flavor. Based in French cuisine, fumét is an important ingredient in several French sauces, such as Normandy sauce. It will also contribute a wonderful flavor when poaching fish and is the basis for Spanish Basque seafood stew

  4. Lower the heat, add the celery, carrot, and onion and warm very gently, with the lid on, for about 5 minutes, or until the onion is softened and slightly translucent but not brown.

  5. Add the fish bones, cover the mixture with a piece of parchment paper, and re-cover the pot, letting the bones warm gently until they are slightly opaque.

  6. Remove the lid and the parchment; add the wine and turn up the heat until the stock starts to simmer.

How to Use

  • Fish stock is used in many different recipes. Use it to make a seafood bisque, étouffée, or gumbo. It is also an important addition in sauces, chowders and stews.

Tip

  • The best fish bones to use for making fish stock are ones from mild, lean, white fish like halibut, cod, or flounder. As a general rule, you'll want to avoid salmon, trout, mackerel, or other oily, fatty fish since their strong flavor will likely overpower your finished dish. (Unless you're specifically making salmon broth, for example, then salmon bones will produce a stock with unbelievably deep, rich salmon flavor.)

How to Store and Freeze

  • Fresh fish stock will last for three to four days in the refrigerator in an airtight container.
  • You can freeze fish stock by placing it in freezer bags or an airtight container. We prefer freezer bags as they take up less space. Fish stock will last frozen for up to two months.
