Fish Stock

Refrigerate in an airtight container immediately after cooling. Freezer storage extends shelf life significantly. If kept in the fridge longer than 3 days, it may develop off-flavors or spoil.

Use bones and trimmings from white fish (cod, halibut, sole) rather than oily fish, which can make stock taste fishy and bitter.

Simmer gently for 30–40 minutes; longer cooking extracts unpleasant flavors.

Strain through cheesecloth for a crystal-clear stock.

Cool completely before refrigerating or freezing to prevent condensation.

Freeze in ice cube trays for easy portioning.

Bouillabaisse, seafood soups, and chowders

Pan sauces for fish and shellfish

Seafood risotto and paella

Poaching liquid for fish fillets

Boiling instead of simmering, which makes stock cloudy and bitter.

Cooking too long (over 45 minutes), which develops off-flavors.

Using oily fish or unwashed bones, which creates a greasy, fishy-tasting stock.

Storing at room temperature, which causes rapid spoilage.
