Soup Db Poisson, or Fish Soup
Ingredients
Directions
Make the stock
Simmer the cod's head in enough water to cover it, seasoning with pepper, coarse sea salt, mace, celery, parsley, sweet herbs, and onions.
Strain the stock when done.
Stew the cutlets
Prepare fish cutlets by cutting them small and trimming them well.
Stew the cutlets in equal parts water and white wine, just enough to cover them, with butter and lemon juice for 15–20 minutes.
Finish and serve
Add the stewed cutlets to the strained soup.
Thicken the soup with cream and flour.
Serve the soup with the cutlets in a tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod's head
- Gives the stock its body and rich fish flavour as it simmers.
- Fish cutlets
- Provide the flaky fish pieces that are served in the soup.
- White wine
- Adds acidity and aroma while the cutlets stew.
- Cream
- Adds richness and a smooth, velvety texture to the soup.
- Flour
- Thickens the soup by swelling with liquid when heated.
- Butter
- Adds fat and richness to the cutlets as they stew.
The step that matters
Thicken the soup with cream and flour. Flour must be cooked out in the hot liquid to thicken smoothly without lumps or a raw starchy taste. Adding cream too hot or boiling it hard can cause it to curdle, so keep the heat gentle once the cream is in.
Swap the mace
How well each one fits the dish's main ingredients (fish, pepper, celery, parsley, thyme, onion, white wine):
- Marjoramfits better
- Tarragonfits better
- Fennelfits better
- Macethe original
Fit is the average pairing score against fish, pepper, celery, parsley, thyme, onion, white wine. Candidates are from the same food group and used in at least 100 recipes.
