Fish stock! Showing how it is prepared.

Fish stock, also known as "caldo de pescado" in Spanish, is a flavorful broth made from fish bones and other ingredients. It is a foundation for many delicious seafood-based dishes and is also a great way to add depth and richness to various recipes. In this article, we will take a closer look at how to prepare fish stock.

To begin, you will need a variety of fish bones and trimmings. These can include heads, tails, bones, and fins. The type of fish used will impact the flavor of the stock, so it is recommended to use a combination of both lean fish such as cod or haddock, and oily fish such as salmon or mackerel.


Make sure the fish is fresh, as the quality of the ingredients will greatly influence the final product.

Once you have gathered the fish bones and trimmings, thoroughly rinse them under cold water to remove any impurities. It is essential to remove any blood or excess fat, as these can create unwanted flavors and cloudy appearance in the stock.

Next, fill a large pot with water and add the fish bones and trimmings. The amount of water will depend on how much stock you want to make, but as a general rule, use enough water to cover the ingredients completely. For additional flavor, you can also add aromatic vegetables such as onions, carrots, celery, and garlic.


These vegetables will not only enhance the taste but also lend a subtle sweetness to the stock.

Simmer the stock over medium heat, making sure not to bring it to a boil as this can make the stock cloudy. Skim off any impurities that rise to the surface with a slotted spoon or a skimmer. This will help maintain a clear and clean stock.

Allow the stock to cook for about 30 minutes to an hour. During this time, the fish bones will release their flavors into the water, infusing it with a savory taste. Be cautious not to overcook the stock as it can become bitter.

Once the stock has simmered and developed a rich flavor, strain it through a fine mesh sieve or a cheesecloth to remove any solids.


Press lightly on the solids to extract as much liquid as possible. Allow the stock to cool before transferring it to airtight containers for storage. It can be refrigerated for a few days or frozen for later use.

In conclusion, fish stock is a vital ingredient in many seafood dishes, providing a robust and flavorful base. By using fresh fish bones and trimmings, along with aromatic vegetables, you can easily make your own homemade fish stock. With its versatility and ability to enhance various recipes, fish stock is a valuable asset in any kitchen.
