Making Basic Fish Stock
A good stock relies on sourcing heads and frames from lean, non-oily white fish like snapper, cod, or halibut. Keep your aromatics restrained to let the clean, oceanic base remain the focus.
Cleanliness is the priority for a clear broth.
Ensure the fish frames are thoroughly rinsed under cold water to remove all traces of blood and dark membranes, which are the primary culprits behind a muddy, off-tasting stock.

What goes in.
- 2-3 lbwhite fish frames, gills removed
- 1yellow onion, thinly sliced
- 1leek, white and light green parts only, cleaned
- 2 stalkscelery, chopped
- 1/2 cupdry white wine
- 3 qtcold water
- 3-4parsley stems
- 1bay leaf
Gentle Simmering
Never let the pot reach a rolling boil. A gentle, lazy bubble prevents the fat and impurities from emulsifying into the liquid, keeping the stock transparent.
The method.
Prepare the bones
Rinse the fish frames under cold running water. Use scissors to snip away the gills and any large dark kidney remnants along the spine.
Sweat the aromatics
In the stockpot over medium heat, soften the onions, leeks, and celery in a splash of oil until they are translucent but not browned.
Deglaze
Pour in the white wine and increase the heat slightly, scraping the bottom of the pot until the liquid has reduced by half.
Simmer
Add the fish bones, parsley, and bay leaf. Cover with cold water. Bring to a bare simmer, then reduce heat to low and cook for 20-25 minutes, skimming any foam that rises to the surface.
Strain
Line your fine-mesh strainer with cheesecloth. Gently ladle the stock through the strainer into a clean container. Do not press on the solids.
Other turns to take.
Fumet
Increase the wine ratio and sweat the bones with the vegetables for 5 minutes before adding water to intensify the acidity and depth.
Asian-Style
Substitute the celery and leeks with smashed ginger, green onion whites, and a few whole peppercorns.
When it doesn't go to plan.
Always remove the gills, as they turn the stock intensely bitter.
Avoid oily fish like salmon or mackerel; their high fat content creates an opaque, heavy stock.
Chill the stock immediately in an ice bath before refrigerating to prevent bacterial growth.
The ones that keep coming up.
Can I freeze fish stock?
Yes. It keeps well in airtight containers or ice cube trays for up to three months.
Why is my stock cloudy?
Usually, this happens because the stock was boiled too hard or the fish bones weren't rinsed well enough of blood before cooking.
