Jump to Recipe

Spanish fish stock, known as fumet de pescado, is a light but flavorful broth used as the foundation for seafood rice, paella, soups, sauces, and fish stews. White fish bones are simmered briefly with aromatic vegetables, herbs, and peppercorns to capture their flavor without producing bitterness.

Unlike meat stock, fish fumet requires only about 30 minutes of cooking. Careful skimming and fine straining produce a cleaner broth that can be refrigerated for immediate use or frozen in practical portions for future recipes.

Ingredient Notes

White fish bones

Use fresh bones, heads, and trimmings from mild white fish. The bones may retain a small amount of flesh, but the gills, entrails, and large patches of blood should be removed.

Leek

Leeks add gentle onion flavor without overpowering the fish. Split and rinse them thoroughly because grit often collects between their layers.

Aromatic vegetables

Carrot, onion, celery, and leek provide sweetness and balance. Rough chopping is sufficient because the vegetables will be strained out.

Bay leaf and parsley

These herbs add a subtle savory aroma while allowing the fish flavor to remain dominant. Avoid adding too many strong herbs.

Cold water

Beginning with cold water allows flavor to extract gradually from the fish bones and gives impurities time to rise to the surface for skimming.

Expert Tips

Use the freshest fish bones available because their aroma and flavor determine the quality of the finished stock.
Remove the gills from fish heads, as they can give the broth an unpleasant bitter or metallic taste.
Start with cold water and skim repeatedly as the liquid heats rather than waiting until it reaches a full boil.
Maintain a gentle simmer instead of a vigorous boil to keep the stock clear and delicately flavored.
Do not stir or crush the bones while they cook, since this can release impurities and cloud the liquid.
Strain the fumet without pressing heavily on the solids, then cool it quickly before refrigerating.

Serving Suggestions

Use the stock as the cooking liquid for paella, arroz caldoso, seafood fideuà, risotto, or other rice and noodle dishes.

Add it to fish soups, seafood chowders, bisques, sauces, and stews for a deeper marine flavor.

Reduce the stock gently to concentrate it before using it in pan sauces or seafood gravies.

Freeze it in 1-cup containers or ice cube trays so small amounts are available for sauces and individual dishes.

Storage and Reheating

Cool the strained stock promptly and refrigerate it in airtight containers for up to 3 days. Freeze it for up to 3 months, leaving space in each container for expansion. Thaw frozen stock overnight in the refrigerator or heat it directly from frozen in a saucepan. Bring refrigerated or thawed stock to a full simmer before using it in another recipe.

Frequently Asked Questions

Which fish bones are best for making fumet?

Use bones and heads from mild white fish such as hake, cod, sole, sea bass, snapper, or halibut. Avoid oily fish because their flavor can become too strong.

Why should fish stock cook for only 30 minutes?

Fish bones release their flavor quickly. Prolonged cooking can extract bitter, chalky, or overly strong flavors and may make the broth cloudy.

How can I keep homemade fish stock clear?

Begin with cold water, skim away foam as the stock heats, maintain a gentle simmer, avoid stirring, and strain the liquid through a very fine filter.

Can I freeze Spanish fish stock?

Yes. Cool it completely, divide it among freezer-safe containers, and freeze it for up to 3 months. Smaller portions are especially convenient for sauces and rice dishes.

Ingredients

2 pounds (1 kg) white fish bones, heads, and clean trimmings
20 cups (5 liters) cold water
1 medium carrot, about 3.5 ounces (100 g), roughly chopped
1 medium leek, white and light green parts only, about 3.5 ounces (100 g), thoroughly rinsed and sliced
1 celery stalk, about 1.8 ounces (50 g), roughly chopped
1 small yellow onion, about 3.5 ounces (100 g), quartered
8 black peppercorns
1 bay leaf
6 fresh flat-leaf parsley sprigs
Fine salt, to taste

Instructions

Rinse the fish bones and trimmings under cold running water, removing any visible blood, dark membranes, and gills.
Place the cleaned fish bones, carrot, leek, celery, onion, peppercorns, bay leaf, and parsley in a tall stockpot.
Pour in the cold water and set the pot over high heat.
As the water heats, use a fine-mesh skimmer or large spoon to remove the gray foam and impurities that rise to the surface.
When the stock reaches a boil, add a small splash of cold water to settle the surface, skim it once more, and allow it to return to a gentle boil.
Reduce the heat and simmer gently, uncovered, for 30 minutes. Avoid vigorous boiling, which can make the stock cloudy and harsh-tasting.
Remove the pot from the heat and season lightly with salt, keeping in mind that the stock may later be reduced or added to another seasoned recipe.
Pour the stock through a fine-mesh strainer lined with cheesecloth, a clean thin kitchen towel, or a paper coffee filter. Do not press firmly on the solids.
Cool the strained stock promptly, then transfer it to covered containers for refrigeration or freezing.

Notes

Ask a seafood counter for white fish frames, bones, or heads. Bones from hake, cod, sole, sea bass, snapper, or halibut are suitable practical options in the United States.

Avoid strongly oily fish such as salmon, sardines, or mackerel because they can produce a heavy, overpowering stock.

Remove the gills and rinse away visible blood before cooking, as both can make the finished fumet bitter or cloudy.

Fish stock needs only a short simmer. Cooking it much longer than 30 to 40 minutes can extract bitter flavors from the bones.

The calorie estimate reflects the modest amount of fish, vegetable, and herb nutrients transferred into the strained liquid; the bones and cooked solids are discarded.
