Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flounders or small flat fish
- Their flesh breaks down during stewing, giving the stock its body and fish flavour.
- Veal broth
- Forms the liquid base that carries the flavour of the fish and vegetables.
- Butter
- Adds richness and fat to the finished stock.
- Flour
- Thickens the stock so it has more body.
- White wine
- Adds acidity and aroma to the stock.
The step that matters
Stewing until the fish passes through a coarse sieve. The fish must cook long enough to fall apart fully, so its flesh and bones release flavour and body into the liquid. Undercooked fish will not pass through the sieve and leaves the stock weak and gritty.
