Ingredients
Directions
Prepare the fish
Gut and clean the flounders and perch carefully.
Make the stock
Put the fish into a stewpan with the veal broth.
Add the ham, carrots, celery, onions, sweet herbs, salt, and cayenne.
Stew until the fish can pass through a coarse sieve.
Return the mixture to the stewpan with butter and flour to thicken.
Add the white wine and garlic vinegar.
For added flavor, include gravy from potted herrings or anchovies.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flounders
- Break down during stewing to give the stock body and fish flavor.
- Veal broth
- Forms the liquid base that carries flavor from the fish and vegetables.
- Butter
- Enriches the stock and carries flavor as part of the thickening mixture.
- Flour
- Thickens the stock when cooked with butter, giving it a fuller texture.
- White wine
- Adds acidity and aromatic depth to the stock.
The step that matters
Stew until the fish can pass through a coarse sieve. The fish must cook long enough to break down fully so its flavor and body dissolve into the liquid. Stopping early leaves the stock thin and weakly flavored, while overcooking can make it cloudy.
