Quick Fish Stock
You do not need a stockpot simmering all day to pull flavor from fish. By keeping the aromatics sliced thin and the liquid levels tight, you can produce a clear, usable base in the time it takes to finish the rest of your prep.
Commit to the white fish rule.
Avoid oily fish like salmon, mackerel, or bluefish, as they will overpower the broth and create a muddy finish. Stick to bones from snapper, cod, halibut, or flounder.
- 3-quart saucepan
- fine-mesh strainer
- cheesecloth
- chef's knife
What goes in.
- 1.5 lbwhite fish bones and heads, cleaned and gills removed
- 1fennel bulb, thinly sliced
- 1leek, white and light green parts only, cleaned well
- 1small yellow onion, sliced into slivers
- 1/2 cupdry white wine
- 4 cupscold filtered water
- 2parsley stems
- 1bay leaf
Sweat, don't brown
You want the vegetables to soften and release their moisture without catching any color. If you brown the onions or leeks, the stock will turn dark and lose the clean, oceanic profile you need.
The method.
Sweat the aromatics
Place the fennel, leek, and onion in the saucepan with a splash of oil over medium-low heat. Cook for 5 minutes until they collapse and smell sweet, but before they show any amber color.
Deglaze the pan
Add the white wine to the pan. Scrape the bottom with a wooden spoon to release anything stuck to the metal, then let the liquid reduce by half.
Add the frames
Lay the fish bones and heads on top of the vegetables. Add the water, parsley, and bay leaf until the bones are just barely covered.
Gentle simmer
Bring the water to a very faint bubble. Skim off any gray foam that rises to the surface using a shallow spoon. Reduce heat to low and keep it there for exactly 25 minutes.
Strain
Line your strainer with a double layer of dampened cheesecloth. Pour the stock through slowly. Do not press on the solids, as this forces particles through and clouds the liquid.
Other turns to take.
Thai-Inspired
Add two smashed lemongrass stalks and a few slices of galangal during the final 10 minutes of simmering.
Deep Sea
Add a small piece of dried kombu to the cold water; remove it just before the water hits a simmer.
When it doesn't go to plan.
Always remove the gills from the fish head before starting; they are the primary source of bitterness and metallic flavors in fish stock.
If you aren't using the stock immediately, freeze it in ice cube trays for easy portioning later.
Keep your fish frames on ice if you aren't using them the moment the fish is filleted; freshness here is everything.
The ones that keep coming up.
Why does my fish stock turn cloudy?
Usually because of a hard boil or because the fish frames weren't cleaned of blood before adding them to the water. Always rinse your bones in cold water until the water runs clear before starting.
Can I use celery?
Celery is often too aggressive for fish stock. Fennel or the white parts of leeks are much better companions for the delicate flavor of white fish.
